1.1 Oracle Service Bus Overview
Oracle Service Bus is a configurationbased, policydriven enterprise service bus
designed for SOA life cycle management. It provides foundation capabilities for service
discovery and intermediation, rapid service provisioning and deployment, and governance.
Service Bus provides scalable and reliable serviceoriented integration, service
management, and traditional message brokering across heterogeneous environments. It
combines intelligent message brokering with routing and transformation of messages,
along with service monitoring and administration. Service Bus leverages industry
standards to connect services and support a high level of heterogeneity, connecting your
existing middleware, applications, and data sources, and protecting existing investments.
Service Bus adheres to the SOA principles of building coarsegrained, loosely coupled,
and standardsbased services, creating a neutral container in which business functions
can connect service consumers and backend business services, regardless of the
underlying infrastructure. The following figure illustrates the role of Service Bus as a
service intermediary in an enterprise IT SOA landscape.

1.1.1 Functional Areas
The following diagram illustrates the primary functional areas of Service Bus, including
virtualization, messaging, security, configuration, and runtime management.

1.1.2 Adaptive Messaging
Adaptive messaging provides flexible message handling and manipulation between clients
and services. For example, a client sends a SOAP message over HTTP through Service
Bus, which in turn transforms the message and invokes a backend EJB. Or a client sends
a REST/JSON message over HTTP, and Service Bus transforms the message and
invokes a backend SOAP/XML service (or uses any of the available adapters). Adaptive
messaging also supports a variety of communication patterns such as request/response,
synchronous and asynchronous, splitjoin, and publish/subscribe. It supports different
patterns for inbound and outbound messages in a single message life cycle.
()
()
1.1.3 Service Security
Service Bus ensures service security at all levels, based on Oracle Platform Security
Services and Oracle Web Services Manager (OWSM) for web services. You can plug in
custom or thirdparty security components. Builtin capabilities allow flexibility in
implementation by enabling security at the following levels:
Transportlevel security, including SSL, basic authorization, and custom security
credentials
Messagelevel security, including WSSecurity, SAML, user ID and password, X509,
signing and encryption, and custom security credentials
Console security, including singlesignon and rolebased access
Policy security
()
()
1.1.4 Service Virtualization

Service virtualization provides agility through message manipulation and control. Service
Bus lets you flexibly control messages using validation, transformation, routing based on
message content, parallel processing of multiple items in a message, alert triggering, and
error handling at different points in a message flow. For example, Service Bus provides
the following capabilities:
XQuerybased policies or callouts to external services for message routing.
Routing policies that apply to both pointtopoint and onetomany routing scenarios
(publish). For publish, routing policies serve as subscription filters.
Routing table abstracted from pipelines, which enables modification of routes without
having to reconfigure pipelines.
Identitybased routing, to classify clients into userdefined groups and apply routing
policies based on these groups.
Conditional routing, including dynamic contentbased routing of messages and runtime
protocol selection.
Database lookups, which can be used for message enrichment, routing decisions, or
customizing the behavior of a pipeline.
Transformations using XQuery or XSLT maps.
()
()
1.1.5 Configuration Framework
The Configuration Framework gives you full control over your Service Bus production
environment and its associated resources.The framework includes session management,
the Test Console, and import/export tools. Service Bus configurations are managed in
sessions, which provide the unique ability to lock the current configuration while changes
are being made. Service Bus can continue to receive and process requests for services
while configuration changes are being made in a session. These changes do not affect the
runtime configuration until you activate the current session. This way, ongoing changes
can be made without disrupting services. Configuration and resource changes you make
are tracked, and you can undo or redo changes, resolve conflicts, maintain dependencies
among resources, and test changes in the Test Console.
The builtin Test Console is a browserbased test environment used to validate resources
as well as inline expressions used in pipelines or splitjoins. Use the Test Console to
configure the test object (such as a pipeline, business service, or XQuery expression),
execute the test, and view test results. It allows message flow tracing when testing a
service, to examine the state of the message at specific trace points.
Service Bus allows the propagation of configuration data from environment to environment
by exporting and importing resources and projects. For example, you can transfer
configurations from a development domain to a test domain to a production domain. The
import and export features let you maintain resource dependencies and preserve
environment values between environments.
The Configuration Framework also includes a metadatadriven interface for service
discovery, publishing, and synchronization using UDDI registries, including automatic
import and synchronization of services with UDDI.
()

()
1.1.6 Service Management
Service management includes a powerful set of runtime configuration tools for monitoring,
alerting, and reporting. Service Bus is fully integrated with Fusion Middleware Control for
SOAwide service management. Service management lets you do the following:
Gather statistics about message invocations, errors, performance characteristics,
messages passed, and SLA violations.
Send SLA and pipeline alerts as SNMP traps, enabling integration with thirdparty
enterprise system management solutions.
Log selected parts of messages for both systems operations and business auditing
purposes.
Search message reports by extracting key information from a message, which can then
be used as a search index.
Integrate with widely adopted thirdparty reporting tools as well as custom enterprise
system management frameworks.
Support open interfaces for operational and deployment customization, JMX monitoring
interfaces, and SNMP Alerts.

()
1.2 Service Bus Architectural Concepts
Service Bus is an intermediary that processes incoming service request messages,
determines routing logic, and transforms those messages for compatibility with other
service consumers. It receives messages through a transport protocol such as HTTP(S),
JMS, File, or FTP, and sends messages through the same or a different transport protocol.
Service response messages follow the inverse path. Message processing by Service Bus
is driven by metadata, specified in the message flow definition (pipeline).
Service Bus provides message delivery services based on standards including SOAP,
HTTP, and Java Messaging Service (JMS). It supports XML as a native data type, while
also offering alternatives for handling other data types. Service Bus lets you establish
loose coupling between service clients and business services, while maintaining a
centralized point of security control and monitoring. It stores persistent policy, service, and
related resource configurations in metadata, which can be customized and propagated
from development through staging to production environments. The messagebrokering
engine accesses this configuration information from its metadata cache.
() ()
()
1.2.1 Message Processing
Messages can contain data or status information about application processes, as well as
instructions for the recipient. Service Bus lets you route messages based on their contents
and perform transformations on that content. The processing happens through the
transport and binding layers of Service Bus.

The processing of messages through Service Bus occurs in the following sequence of
events:
1. A client sends a message to Service Bus using a specific transport protocol.
2. A transport provider processes the inbound message, handling communication with the
service client endpoint and acting as the entry point for messages into Service Bus.
3. The binding layer packs and unpacks messages, handles message security, and hands
messages off to the pipeline.
4. The pipeline performs any transformation, validation, logging, and reporting, and then
routes the message to an endpoint (either a business service or another proxy service).
5. Service Bus processes the response message in a similar manner as the above steps.
The following figure illustrates the flow of data through Service Bus, from inbound
endpoint (proxy service) to outbound endpoint (in this case, a business service). The
transports listed are a subset of those available through Service Bus.
Figure 13 Oracle Service Bus Message Processing
Description of "Figure 13 Oracle Service Bus Message Processing" (img_text/GUID613D2B6DE6934EC08C53
2AAF384F1263.htm)
The following sections describe each layer involved in this message processing.
()
()
1.2.2 Proxy Service Role in Message Processing
Proxy services are the interfaces that service consumers use to connect with managed
backend services. Proxy services are definitions of intermediary web services that
Service Bus implements locally. The proxy service interface is defined in terms of Web
Services Description Language (WSDL) or Web Application Definition Language (WADL)
and the type of transport it uses.
()
()
1.2.3 Transport Layer (Inbound)
The inbound transport layer is the communication layer between client services (or service
consumers) and Service Bus. It is responsible for handling communication with the service
client endpoint and acts as the entry point for messages into Service Bus. The inbound
transport layer primarily deals with raw bytes of message data in the form of input/output
streams. The transport layer provides support for compatible transport protocols, including

HTTP(S), JMS, FTP, File, email, and others. It is not involved in data processing but is
responsible for returning response messages to service consumers and handles metadata
for messages, including endpoint URIs, transport headers, and so on.
()
()
1.2.4 Binding Layer
The binding layer for both inbound and outbound performs the following functions in
message processing:
Packs and unpacks messages as necessary
Handles security for messages
Hands messages off to start the pipeline (request and response)
()
()
1.2.5 Pipeline Role in Message Processing
A pipeline defines the flow of request and response messages through Service Bus,
including routing, transformations, validations, publishing, reporting and exception
management. It accepts messages from the binding layer of the proxy service, performs
any transformations or validations, and then forwards the message to the binding layer of
the outbound service, either a proxy or business service. Along the way, the pipeline can
make callouts to other services, Java objects, or POJOs.
()
()
1.2.6 Transport Layer (Outbound)
The outbound transport layer is responsible for the communication between external
services (or service producers) and Service Bus. It is responsible for moving messages
from Service Bus to the business service or proxy service and for receiving the response
from the services. At the transport level, the message data are in raw bytes in the form of
input/output streams. The outbound transport layer provides support for compatible
transport protocols, including HTTP(S), JMS, FTP, File, email, and others. It is not
involved in data processing but handles metadata for messages, including endpoint URIs,
transport headers, and so on.
()
()
1.2.7 Business Service Role in Message Processing
Business services are the interfaces that connect with service producers. The business
service interface is defined in terms of Web Services Description Language (WSDL) or
Web Application Definition Language (WADL) and the type of transport it uses.
()
()
1.3 Service Bus Components
Service Bus routes message between external services (such as enterprise services and
databases) and service clients (such as presentation applications or other business
services). The service and flow components you create in a Service Bus project rely on

local and system resources in Service Bus to define additional information like user names
and passwords, keystore credentials, server connections, and transformations.
Service Bus resources are reusable definitions of entities that typically include metadata
for those entities. Resources can be used by multiple services and provide standardized
definitions or descriptions for use across an enterprise or department.
()
()
1.3.1 Service Components
Proxy services and business services define the endpoints in a Service Bus system. They
include the binding and transport layers, and are the points at which Service Bus
communicates with external services, including producers and consumers.
()
()
1.3.1.1 Proxy Services
Proxy services are Service Bus definitions of generic intermediary web services that are
hosted locally on Service Bus. A proxy service communicates with external services
through interfaces, which may or may not be identical to that of a service provider or
service consumer business service. Through pipelines, you can route messages from a
proxy service to multiple business services using their configured independent interfaces.
A proxy service's configuration includes its interface (service type), the type and
configuration of the transport it uses to connect with client services, security requirements,
and service level agreement (SLA) alert rules. When a proxy service interfaces with
multiple business services, its associated pipeline is configured to route messages to the
appropriate business service and map the message data into the format required by the
business service's interface.
For more information, see Creating and Configuring Proxy Services (GUIDC7FA8DADE235
437F87D83FE28BE98A6D.htm#GUIDC7FA8DADE235437F87D83FE28BE98A6D).
()
()
1.3.1.2 Business Services
Business services are Service Bus definitions of the enterprise services that exchange
messages during business processes. A business service's configuration includes its
interface (service type), the type and configuration of transport it uses to connect with
service producers, security requirements, message handling, performance tuning, and
SLA alert rules. A business service also specifies the endpoint URI, and can specify
multiple endpoints for load balancing and high availability. A business service definition is
similar to that of a proxy service, but with additional options for message handling,
endpoint throttling, and result caching, which help improve performance.
You can create a service account to provide authentication when connecting to a business
service. It acts as an alias resource for the required user name and password pair. You
can also use Oracle WebLogic Server to directly manage security credentials for a
business service requiring credentiallevel validation.
For more information, see Creating and Configuring Business Services (GUIDB932E48E
8DDA4C3DB600CBE2C510CED6.htm#GUIDB932E48E8DDA4C3DB600CBE2C510CED6).

()
1.3.2 Message Flows

A message flow defines how messages are routed, validated, and transformed between
services. The message flow is typically defined in a pipeline, but can also be defined in a
splitjoin for parallel processing.

Pipelines define message routing and transformation logic, as well as message handling
options. This logic includes activities such as transformation, publishing, logging,
reporting, alerts, and exception management. Each of these activities are configured as
individual actions within the message flow. Both JDeveloper and the Oracle Service Bus
Console provide graphical modeling tools to help you model your pipelines.
The following primary elements are used to construct a pipeline:
A start node.
A pipeline pair, one for the request and one for the response. Each pipeline in a pair
consists of a sequence of stages that specify actions to perform during request or
response processing.
A branch node, to branch based on the values in designated parts of the message or
message context, or to branch based on the operation invoked.
A route node, to define the message destination. The default route node is an echo
node that reflects the request as the response.
An error handler, which can be attached to any node or stage to handle potential errors
at that location.
At a minimum, a start node and route node are required. While an error handler is not
required, it is recommended. If an instance fails and no error handler is defined, the error
is not recoverable. Pipeline elements can be combined in arbitrary ways to form a tree
structure with the start node always (and only) occurring as the root of the tree and the
route nodes. The last nodes in a branch (leaf nodes) can be route nodes or echo nodes.
Since a pipeline can route messages to multiple business services, a pipeline can be
configured with an interface that is independent of the business services it communicates
with. Using generic templates, the pipeline can be a configured to dynamically route
messages to appropriate business services based on contentbased routing logic. A
pipeline can also map message data into appropriate protocol formats required by the
endpoint business service, allowing for dynamic runtime protocol switching.

1.3.2.1.1 How Data Flows Through a Pipeline
In a pipeline, the request message starts at the start node and follows a path to a leaf
node, executing actions in the request pipelines. If the leaf is a route node, a response is
generated. If the leaf is an echo node, the request is also considered to be the response.
The response follows the inverse path in the tree, skipping actions in the branch nodes but
executing actions in response pipelines. A response is then sent from the top of the tree if
the interface or operation was request/response; otherwise the response is discarded.

A set of transformations that affects context variables can be defined before the message
is sent to the selected endpoint or after the response is received. A web services callout
can be an alternative to an XQuery or XSLT transformation to set the context variables.
()
()
1.3.2.1.2 Message Context
The context of a pipeline is a set of XML variables that are shared across the request flow
and response flow. New variables can be dynamically added or deleted to the context, and
these variables can be shared across multiple pipelines or used locally within one pipeline.
Predefined context variables contain information about the message, transport headers,
security principles, metadata for the current pipeline, and metadata for the primary routing
and publishing services invoked by the pipeline.
The context can be read and modified by XQuery or XSLT expressions, and updated by
transformation and inplace update actions. The core of the context contains the variables
$header , $body , and $attachments . These wrapper variables contain the Simple
Object Access Protocol (SOAP) header elements, SOAP body element, and Multipurpose
Internet Mail Extensions (MIME) attachments, respectively. The context gives the
impression that all messages are SOAP messages, and nonSOAP messages are
mapped to this paradigm.
()
()
1.3.2.2 SplitJoins
The splitjoin message flow improves service performance by splitting a message payload
and processing multiple operations in a message simultaneously and then combining, or
joining, all results. A standard pipeline processes operations one after another.
The following primary elements are used to construct a message flow in a splitjoin:
A start node, which contains the request and response variables introspected from the
WSDL operation.
A receive node, to receive incoming request messages.
A reply node, to send response messages.
A scope, which is a container that creates a context that influences the behavior of its
enclosed elements.
A parallel node, which is a placeholder for a fixed number of processing branches, each
with its own scope.
The available elements can be combined in arbitrary ways to form a tree structure with the
start node always (and only) occurring as the root of the tree. The last node is always the
reply.
For more information, see Improving Service Performance with SplitJoin (GUID6910F50F

1.3.3 Transports, Adapters, and Bindings

Service Bus provides connectivity to external systems through a variety of transports,
each of which is specific to a type of external system. Service Bus supports optimized
database queries, and interoperability with web service integration technologies such as
.NET, IBM MQ Series, IBM WebSphere, Apache Axis, and iWay adapters. The JCA
transport expands the list of supported technologies by letting you connect to external
systems using Oracle JCA technology and applications adapters. Additionally, Service Bus
supports the REST binding, allowing you to connect to RESTful services using the HTTP
transport.
You configure a transport's processing and connectivity information directly within a proxy
or business service; you configure Oracle adapters using a configuration wizard specific to
each adapter.
For more information, see Working with JCA Adapters, Transports, and Bindings (GUID
ABAFDA2E21944970BCA09C642AE8613F.htm)
()
()
1.3.3.1 Supported Transport Protocols
Service Bus supports the following transport protocols:
DSP (Oracle Data Service Integrator)
EJB/RMI
Email (POP/SMTP/IMAP)
File
(S)FTP
HTTP(S)
JCA
JEJB
JMS (including MQ using JMS, and JMS/XA)
Local (Oracle proprietary for interESB communication)
MQ (WebSphere MQ)
SB (RMI support)
SOADIRECT (Oracle SOA Suite) and BPEL
Tuxedo (Oracle Tuxedo)
WS (Web Services Reliable Messaging
Service Bus also provides the Custom Transport SDK so you can create new transports to
connect with systems not covered above.
()
()
1.3.3.2 Service Types
Service Bus supports a variety of service types ranging from conventional web services
(using XML or SOAP bindings in WSDL files) to nonXML (generic) services. You select
and configure the service type when you create a business or proxy service. The available
service types for a proxy or business service depend on the transport being used. Service
Bus supports request and response as well as oneway paradigms, for both the HTTP and
the JMS asynchronous transport protocols. If the underlying transport supports ordered
delivery of messages, Service Bus also extends the same support.

Not all service types can be used with all transport protocols. The following table shows
the service types and the transport protocols they support.

The BPEL10g, DSP, EJB, and SOADIRECT transports are only supported with business
services.
()
()
1.3.4 Transformation Resources
In addition to creating inline XQuery expressions directly in message flow actions, you can
reference transformation maps that define more complex mappings between source and
destination services. When disparate message data types exist between source and
destination services, data mapping ensures service compatibility. Service Bus supports
data mapping using XQuery and eXtensible Stylesheet Language Transformation (XSLT)
standards, along with XPath expressions. You can also use cross reference tables and
domain value maps to map field values between services.
Messages can be transformed in the following ways:
Using XQuery or XSLT to reformat the message structure.
Manipulating message content by adding, removing, or replacing certain data elements.
Using cross reference or domain value map tables to map entities across systems.
()
()
1.3.4.1 XQuery Mappings

The XQuery Mapper in JDeveloper is a graphical tool that lets you define mappings that
transform data between XML, nonXML, and Java data types so you can rapidly integrate
heterogeneous applications. For example, XML data that is valid against one schema can
be converted to XML that is valid against a different schema. The data can be based on
XML schemas, Web Service Definition Language (WSDL) files, and Message Format
Language (MFL) files. You can create an XQuery mapping in JDeveloper, and then upload
the .xqy file generated by the mapper to an XQuery resource in the Oracle Service Bus
Console. XQuery mappings are stored in XQuery resources in Service Bus, which can be
referenced from the expressions you create using the expression editors in a message
flow action.
The output of the XQuery Mapper is a query in the XQuery language, which is defined by
the World Wide Web Consortium (W3C). For more information about W3C and the
XQuery language, see http://www.w3.org/XML/Query/ (http://www.w3.org/XML/Query/).
For more information, see Transforming Data with XQuery (GUIDF1DC5B1AD85A4F3498EF
757E086D328E.htm#GUIDF1DC5B1AD85A4F3498EF757E086D328E) and "Creating
Transformations with the XQuery Mapper (../../soasuite/developsoa/xquerymapper
transforms.htm#SOASE88074)" in Developing SOA Applications with Oracle SOA Suite.
()
()
1.3.4.2 XSLT Mappings
eXtensible Stylesheet Language Transformation (XSLT) maps describe XMLtoXML
mappings. The XSLT mapper in JDeveloper is a graphical tool that lets you define
mappings between schema root elements, Web Services Description Language (WSDL)
message parts, or WSDL messages. Schema root elements can come from XSD schema
files or WSDL files. Only those WSDL messages that contain a single message part can
be mapped directly.
The XSLT Mapper in JDeveloper lets you define transformations that apply to the whole
message body to convert messages from one XML schema to another, enabling data
interchange among applications that use different schemas. You can create an XSLT
mapping in JDeveloper, and then upload the .xsl file generated by the mapper to an
XSLT resource in the Oracle Service Bus Console. XSLT mappings are stored in XSLT
resources in Service Bus, which can be referenced from the expressions you create using
the expression editors in a message flow action.
For more information, see Transforming Data with XSLT (GUID89ACD1B19A864799A304
7E0D7F840DF7.htm#GUID89ACD1B19A864799A3047E0D7F840DF7) and "Creating
Transformations with the XSLT Mapper (../../soasuite/developsoa/xsltmapper
transformations.htm#SOASE188)" in Developing SOA Applications with Oracle SOA Suite.

()
1.3.4.3 Cross References
Cross reference tables map identifiers that represent equivalent objects across multiple
applications, associating like objects created in different external applications. They are
used to manage the runtime correlation between the various applications that share data
through Service Bus. For example, you can use cross references to map customer
identifiers for records that were created in multiple customer management systems. Cross
reference values can be updated during runtime, allowing you to dynamically integrate
values between systems. Any cross reference data updated at runtime is persisted in the
database. Cross references can be used across Oracle SOA Suite components. In
Service Bus, you can create cross reference tables in both JDeveloper and the Oracle
Service Bus Console.

Service Bus provides a set of XPath functions for looking up and modifying cross
reference values. These functions are available to use in the expressions you create using
the expression editors in a message flow action. For more information, see Mapping Data
with CrossReferences (GUIDF1DED2BCB51346379FAF63F07FAB52A5.htm#GUIDF1DED2BC
B51346379FAF63F07FAB52A5).
()
()
1.3.4.4 Domain Value Maps
A domain value map associates terms used by different domains to describe the same
entity, providing the capability to map the terms across vocabularies or systems. For
example, each domain might use different terminology for country codes, city codes,
currency codes, and so on. You can enter these values in a map and look up those values
at runtime to transform the data when passing it from one domain to another. Domain
value maps are similar to cross references, but they are defined statically rather than
dynamically. You create and populate domain value maps in the design time, and deploy
them to the runtime. Domain value map data are not changed by runtime activities as it is
for cross references, but rather the domain value maps are used for lookups only.
Domain value maps can be used across Oracle SOA Suite components. In Service Bus,
you can create domain value maps in both JDeveloper and the Oracle Service Bus
Console. Service Bus provides a set of XPath functions for looking up domain value map
values. These functions are available to use in the expressions you create using the
expression editors in a message flow action. For more information, see Mapping Data with
Domain Value Maps (GUID7EADE1E02383428D8C3738C8A1A4CD59.htm#GUID7EADE1E02383
428D8C3738C8A1A4CD59).
()
()
1.3.5 Transport and Adapter Related Resources
Some transports rely on specific types of files, such as JavaScript and JAR files or MQ
connections. The JCA transport requires the JCA file and any files it references, such as a
WSDL file. This section describes the resources that are specific to certain transports.
()
()
1.3.5.1 JCA Bindings
JCA binding resources in Service Bus let you create business and proxy services that
interact with external services through Oracle SOA Suite JCA adapters. A JCA binding is
made up of a service WSDL document and a corresponding JCA file created in Oracle
JDeveloper. In JDeveloper, you can add a JCA adapter directly to a Service Bus project
using the Service Bus Overview Editor by dragging and dropping the adapter type from
the Components window to the editor's canvas. The proxy or business service is
automatically generated from the JCA adapter configuration, and is based on the JCA
transport. In the Oracle Service Bus Console, you need to upload the JCA file into a JCA
binding resource in order to create a business or proxy service based on that JCA adapter.
You can also import the JCA file and its associated WSDL file using the import feature.
For more information, see Working with JCA Binding Resources (GUIDB2646D8DD53F469B
BA79E007BC454C2C.htm#GUID12B8E27D5550435EBBAC9C8C55CE8B09).
()
()
1.3.5.2 JAR Files (Archives)
A JAR (Java Archive) is a zipped file that contains a set of Java classes. It is used to store
compiled Java classes and associated metadata that can constitute a program. A JAR
acts like a callable program library for Java code elements, so a single compilation link

provides access to multiple elements rather than requiring bindings for each element
individually.
In JDeveloper, you can add JAR files to a project or component directly from the file
system, but in the Oracle Service Bus Console, you need to upload each JAR file to add
to a project into an archive resource. In Service Bus, JAR files are used the following
components:
Java callout actions (in pipelines) that provide a Java exit mechanism
EJBbased business services
JEJBbased business and proxy services
Tuxedobased proxy and business services
For more information, see Working with JAR Files (GUID1E8A757561F648A79760
A0673D2CA767.htm#GUID303C4A9875894AFBA42D05F6838F4793).
()
()
1.3.5.3 JavaScript Files
JavaScript files are used by the JCA Socket Adapter as a mechanism for handling the
handshake. XSLT and custom Java code are also supported handshake mechanisms. In
JDeveloper, you can create a JavaScript file and then select the file when you configure a
JCA socket adapter. You can also create the JavaScript when you configure the adapter.
In the Oracle Service Bus Console, you can either upload an existing JavaScript file to a
JavaScript resource, or you can create the text for the JavaScript in a text editor in the
console. Alternatively, you can use the console's import feature to import the Socket
adapter's JCA file and its dependencies, such as WSDL and JavaScript files.
Service Bus supports JavaScript handshake for both inbound and outbound socket
adapters, and for oneway and request/response messaging. Request/response
handshakes require a separate JavaScript file for the request and the response.
For more information, see Working with JavaScript Resources (GUIDB2646D8DD53F469B
BA79E007BC454C2C.htm#GUID6CFAF58F02F34F63AB0C5A7E79E54116).
()
()
1.3.5.4 MQ Connections
MQ connection resources provide the connection parameters required to connect to an
MQ queue manager. They are used in proxy and business services configured to use the
MQ transport, and can be shared and reused across multiple services. MQ proxy and
business services must connect to an MQ queue manager before they can access an MQ
queue. Each MQ connection resource uses a connection pool, and every business or
proxy service that connects to a queue manager using the same MQ connection resource
also uses the same connection pool. Thus, multiple business and proxy services can use
the same queue manager and share a connection pool.
In order to create MQ connections in the Oracle Service Bus Console, you must install the
WebSphere MQ client library to the Service Bus domain. This is described in How to
Create MQ Connections (GUID279E650625B14B5C808DDEA724657805.htm#GUID1D125C110805
4349843453C31D13223A).
()
()
1.3.6 Schema and Document Resources

Service Bus services rely on different document types to define information like message
structures and web interfaces. These documents include XML schemas, MFL files, and
XML files to describe data, and WSDL and WADL documents to describe interfaces.
Service Bus has a builtin type system that is available for use at design time. When
creating an XQuery expression in a condition, inplace update action, or transformation,
the variable can be declared to be of a given type in an editor to assist in easily creating
the XQuery. The types can be the following:
XML schema types or elements
WSDL types or elements
MFL types
()
()
1.3.6.1 XML Schemas
XML schemas are documents that define valid content for primitive or structured data in
XML documents. XML schemas specify the structure of documents, the data type of each
element and attribute contained in the document, and the rules that XML business data
must follow. XML schemas can import or include other XML schemas. Schemas are used
to add XML information to messages exchanged in Service Bus, and may be required for
XQuery expressions, WSDL files, and so on.
For more information, see Working with XML Schemas (GUID1E8A757561F648A79760
A0673D2CA767.htm#GUID7E4EA620967A4C86B45375D5F3DB3788).
()
()
1.3.6.2 XML Documents
XML document resources store XML files that can then be referenced when configuring
proxy or business services. For example, you might use XML documents for TopLink
mapping files needed in JCA proxy or business services that communicate with JCA
compliant systems.
XML documents are a standard feature in JDeveloper. In the Oracle Service Bus Console,
the easiest way to create XML documents is to use the import feature. For example, if you
import JCA resources (JCA file, along with its associated WSDL and mapping files),
Service Bus automatically generates XML document resources out of mapping files and
maintains the dependencies among resource files. You can also create an XML document
resource, and upload the contents of an XML file to the resource.
For more information, see Working with XML Documents (GUID1E8A757561F648A79760
A0673D2CA767.htm#GUID5AF8067FCE45402EAFC4526F2E6777E5).
()
()
1.3.6.3 WSDL Documents
A Web Service Definition Language (WSDL) interface defines a service interface for a
SOAP or XML service. For web services, a WSDL document describes what the web
service's interface is, where it resides, and how to invoke it. Service Bus defines proxy
and business services in terms of two WSDL entities:
The abstract WSDL interface, which defines the operations in that interface and the
types of message parts in the operation signature.

The binding WSDL interface, which defines the binding of the message parts to the
message (packaging), and the binding of the message to the transport.
A WSDL file can also describe the concrete interface of the service (for example, the
transport URL).
You can base the definition of a proxy or business service on an existing WSDL file, which
automatically configures portions of the service. WSDL files used as the basis for defining
services are stored as Service Bus resources. In JDeveloper, you can create WSDL files
using the builtin WSDL editor. You can then import those WSDL files, and any schemas
used by the file, into the Oracle Service Bus Console. The console can also be used to
resolve the references in the WSDL files, ensuring all schemas and WSDL files are linked
correctly. Service Bus uses its own representation of the interface for messaging services.
For more information, see Working with WSDL Documents (GUID74E456BD7C5243ACA666
DD07760CF81A.htm#GUID74E456BD7C5243ACA666DD07760CF81A).
()
()
1.3.6.4 WADL Documents
A Web Application Definition Language (WADL) document is similar to a WSDL document,
described above, but it is specifically used to described the interface for REST proxy or
business services. When you create a proxy or business service based on the REST
binding in JDeveloper, the required WADL document is automatically generated from the
WSDL document you specify for the binding. A WADL file can have dependencies on a
WSDL file and on one or more XML schemas.
If you are using the Oracle Service Bus Console, you can create WADL documents by
importing them or by creating a WADL resource. For more information, see Creating
WADL Documents (GUIDC346DF7D041D4E10BE1C451F50719106.htm#GUID3CF8739497654F9A
A506D2B31AD170D5).
()
()
1.3.6.5 MFL Resources
Service Bus uses Message Format Language (MFL) to describe the structure of typed
nonXML data. MFL is an Oracle proprietary language used to define the rules that
transform formatted binary data into XML data. MFL documents are used at runtime to
transform an instance of a nonXML data record to an instance of an XML document (or
the other way around).
You create MFL documents using the Format Builder tool in JDeveloper. The Format
Builder allows you to describe the layout and hierarchy of the nonXML data so it can be
transformed to or from XML. Using the Format Builder, you define each field in the
message, including the type and size of data, the name of the field, any delimiters, and so
on. You can also indicate whether the field is repeating, and whether it is optional or
required.
For more information, see Defining Data Structures with Message Format Language (GUID
74D53E73CC214505A9E40DE1CE5C3FD6.htm#GUID74D53E73CC214505A9E40DE1CE5C3FD6).
()
()
1.3.7 Security Resources

Security information can be passed through proxy and business services using service
accounts, which define how the user name and password are obtained, or using service
key providers, which define encryption credentials.
()
()
1.3.7.1 Service Key Providers
Service Key Provider resources contain Public Key Infrastructure (PKI) credentials used
by proxy services for decrypting inbound SOAP messages and for outbound
authentication and digital signatures. PKI credentials are private keys paired with
certificates that can be used for digital signatures and encryption (for Web Services
Security) and for outbound SSL authentication. The certificate contains the public key that
corresponds to the private key.
Service Bus uses service key providers to supply the following types of credentiallevel
validation to proxy services.
SSL client authentication
Digital signature
Encryption
Web Services Security X509 token
For more information, see Working with Service Key Providers (GUID1E8A757561F648A7
9760A0673D2CA767.htm#GUID4E5CD2DE93D540ECB4F3A73DE2935DAF).
()
()
1.3.7.2 Service Accounts
Service account resources provide user names and passwords that Service Bus uses for
authentication when connecting to a service or server. Service accounts are used by proxy
and business services for outbound authentication or for authentication to a local or
remote resource, such as an FTP server or a JMS server. You can configure a service
account to use a specific user name and password pair, to use the user names and
passwords received from incoming requests, or to map user names and passwords
provided by clients to user names and passwords you specify. One service account can
be used for multiple business and proxy services.
For more information, see Working with Service Accounts (GUID1E8A757561F648A79760
A0673D2CA767.htm#GUIDB34F9F69CC0E457380727208A8953036).
()
()
1.3.7.3 WSPolicy Resources
In previous versions, WSPolicy resources were used to store custom web service policies
so they could be referenced by multiple WSDL documents. Beginning in 12c, Oracle Web
Services Manager (OWSM) policies replace WLS9 policies, so there is no longer an
option to create new services with WSDLbased WLS9 policies. While WSPolicy
resources are still visible in imported projects, the associated web services should be
updated to use OWSM policies. However, you can still import and activate a project from a
previous version that uses WSPolicy resources.
()
()
1.3.8 Alert Destinations

An alert destination resource defines a list of recipients that can receive alert notifications
from Service Bus. For example, when a service level agreement (SLA) or pipeline alert is
generated, you can specify that notifications be sent to specific email addresses or JMS
queues, ensuring that only the relevant people receive the notifications. An alert
destination could include one or more of the following types of destinations: the Service
Bus reporting data stream, SNMP trap, alert log, email, JMS queue, or JMS topic. In the
case of email and JMS destinations, a destination resource could include a list of email
addresses or JMS URIs, respectively.
For more information, see Working with Alert Destinations (GUID1E8A757561F648A79760
A0673D2CA767.htm#GUID23E4860034E541CCB193C40E462B3862).
()
()
1.3.9 Throttling Group Resources
Throttling helps improve performance and stability by preventing message overload on
hightraffic business services. To control the flow of messages to a business service and
prevent backlogs, you can enable and configure message throttling for a business service
or group of business services in your Service Bus applications. When messages are
throttled, the business service can only concurrently process the number of messages you
specify. When that capacity is reached, messages are stored in an inmemory queue until
the business service is ready to process more messages.
For more information, see "Configuring Business Services for Message Throttling
(../../osb/administer/GUID24DF76ECBB774AAA8A6BEF91518CFD1F.htm#OSBAG614)" in
Administering Oracle Service Bus.

()
1.3.10 System Resources
System resources are globally available resources that can be shared across all projects
in your Service Bus instance. They define server connections and authentication
information, and include the following:
JNDI Providers (GUID2CFA406F66DF44F1894BCFD7EC66CEB1.htm#GUIDD90D7DF009B2
444EA88E57126E4E1C79)

4343BBC493558CA97377)
In the Oracle Service Bus Console, system resources are stored in a separate project
named System. In JDeveloper, system resources are stored in the Application Resources
panel under Service Bus System Resources.
()
()
1.3.10.1 JNDI Providers
JNDI provider resources define the connection and authentication information needed to
access JNDInamed objects. They describe the URL (or list of URLs in the case of
clustered deployments) of the JNDI providers used by Service Bus. For example, in a
business service used to invoke an EJB, you include the name of a JNDI provider

resource in the endpoint URI. When the business service is invoked, Service Bus uses the
details in the referenced JNDI provider resource to make the initial connection to the JNDI
provider.
If the JNDI provider is secured, then the JNDI provider resource also defines a user name
and password to gain access. JNDI providers offer a great deal of flexibility. If a JNDI
connection changes, you only need to modify the JNDI provider resource, and anything

1.3.10.2 SMTP Servers
SMTP server resources define the address of SMTP servers corresponding to email
destinations, port numbers, and, if required, authentication credentials. They describe the
URL for the SMTP servers used by Service Bus. If the SMTP server is secured, the SMTP
server resource description also includes a user name and password to gain access.
SMTP server resources are referenced when configuring alert destination resources and
email transportbased business services.
For more information, see Working with SMTP Server Resources (GUIDAF48FF77297D
48AD894A7882BA6C78E8.htm#GUID5B3384D018DC4672991FBA99D84D0511).
()
()
1.3.10.3 Proxy Servers
Proxy server resources define the connection and authentication information needed to
access JNDInamed objects. They describe the URL for the proxy servers used by Service
Bus. If the proxy server is secured, the proxy server resource description also includes a
user name and password to gain access. You can use a proxy server to proxy requests
from a client application, and you typically use a proxy server when Service Bus is behind
a firewall. When you configure business services to route messages through a proxy
server, associate the proxy server resource with that business service. This instructs
Service Bus to connect to the business service through the configured proxy server.
You can configure multiple proxy servers for each proxy server resource. In this case,
Service Bus can perform load balancing and offer fault tolerance among the configured
proxy servers.
For more information, see Working with Proxy Server Resources (GUIDAF48FF77297D48AD
894A7882BA6C78E8.htm#GUID5A1BC7A40BBD4EDF88B0356216B8AF09).

1.3.10.4 UDDI Registries
Universal Description, Discovery and Integration (UDDI) registries are used to share web
services. UDDI provides a framework in which to classify your business, its services, and
the technical details about the services you want to expose. A UDDI registry resource
stores information about a UDDI registry accessed by Service Bus for service discovery,
publishing, and synchronization. After the UDDI registry resource is configured, you can
publish Service Bus proxy services to the associated registry, or import business services
from the registry to be used by a proxy service. UDDI registry resources define the inquiry,
publish, security, and subscription URLs, along with a user name and password to gain
access to the registry.
For more information, see Working with UDDI Registries (GUIDFA2E58B264DF4EE3B5B6
EA03956AE625.htm#GUIDFA2E58B264DF4EE3B5B6EA03956AE625).

1.4 Service Bus Messaging
This section discusses the types of messaging supported by Service Bus, the message
formats, and the context variables that are passed through, and optionally modified by, the
components in a Service Bus project.
()
()
1.4.1 Messaging Models
Service Bus accommodates multiple messaging paradigms and supports the following
types of communication:
Synchronous request/response
Asynchronous publish onetoone
Asynchronous publish onetomany
Asynchronous request/response (synchronoustoasynchronous bridging)
In syncasync bridging, a synchronous client issues a request to an asynchronous
provider. For this pattern, you can publish a message to one JMS queue and configure a
second JMS queue for the response, with a timeout value for listening for the response.
This type of service appears as a synchronous service to the service consumer. Using
asynchronous request/response messages has these advantages:
No blocking by the request thread, removing thread management issues that can occur
when numerous blocking request/response invocations are made.
More reliable messaging.
()
()
1.4.2 Message Formats
Service Bus supports the following message formats:
Email with or without attachments
Java
JMS with headers
MFL (Message Format Language)
Raw Data (opaque nonXML data with no known schema)
Text

SOAP and SOAP with attachments (SOAP described or not described by a WSDL
document)
XML and XML with attachments (XML described or not described by a WSDL document
or a schema)
()
()
1.4.3 Message Context
All messages sent to and received by a proxy service are defined internally by a set of
properties that hold the message data and metadata related to that message. This set of
properties is known as the message context and is implemented using context variables.
The context is defined by an XML schema. Some context variables are predefined and
others are user defined.
Predefined context variables contain information about the message, transport headers,
security principals, metadata for the current proxy service, and metadata for the primary
routing and publishing services invoked by the proxy service. You typically use an XQuery
expression in a pipeline to manipulate context variables as a message moves through
Service Bus. You can also modify context variables using transformation and inplace
update actions.
For a complete description of the message context and context variables used in the
message flow, see Message Context (GUID71E8CE2C660C4D26A308FB46F0AAE820.htm#GUID
71E8CE2C660C4D26A308FB46F0AAE820).
()
()
1.4.4 Content Types
To support interoperability with heterogeneous endpoints, Service Bus lets service
configurations control the content type, JMS type, and encoding used. It does not make
assumptions about what the external client or service needs, but instead uses the
configuration of the proxy or business service. Service Bus derives the content type for
outbound messages from the service type and interface and uses the following
specifications:
For XML or SOAP (with or without a WSDL file), the content type is text/XML.
For messaging services when the interface is MFL or binary, the content type is
binary/octetstream.
For messaging services when the interface is text, the content type is text/plain.
For messaging services when the interface is XML, the content type is text/XML.
The content type can be overridden in the outbound context variable ($outbound ) for
pipelines invoking a service, and in the inbound context variable ($inbound ) for a pipeline
response. Additionally, there is a JMS type (byte or text) that can be configured when the
service is defined. Encoding is explicitly configured in the service definition for all
outbound messages.
()
()

1.5 Using Work Managers with Service
Bus
Service Bus uses Oracle WebLogic Server Work Managers to optimize performance and
to maintain servicelevel agreements. Work Managers prioritize work and allocate threads
bases on rules you define and based on runtime performance. When you create and
configure a Work Manager, you define the maximum and minimum number of threads to
use, server capacity, and request and response classes that express scheduling
guidelines. One default Work Manager is provided, but you can create as many Work
Managers as you need to optimize your services. In Service Bus, you specify a Work
Manager for a proxy service or business service in the Dispatch Policy property of the
transport configuration.
For more information about Work Managers, see "Using Work Managers to Optimize
Scheduled Work" (http://www.oracle.com/pls/topic/lookup?ctx=fmw121300&id=CNFGD112) in
Administering Server Environments for Oracle WebLogic Server. For more information
about Work Managers in Service Bus, see Using Work Managers with Service Bus (GUID
FE2CAC5BE4DF49DEAD3C36EEAF750BFE.htm#GUID6C3D3C19B92C43588E512671D06589A6).

()
1.6 Service Bus Security
Service Bus uses Oracle Platform Security Services (OPSS) and Oracle Web Services
Manager (OWSM) as the building blocks for higherlevel security services including
authentication, identity assertion, authorization, role mapping, auditing, and credential
mapping. In order to configure Service Bus access security, you must first configure
Oracle WebLogic Server security. Service Bus uses OWSM to provide a policy framework
to manage and secure web services consistently across your organization.
()
()
1.6.1 Service Bus Security Features
Service Bus provides the following security features:
Integration with OWSM and OPSS
Authentication, encryption and decryption, and digital signatures as defined in the Web
Services Security (WSSecurity) specification
SSL to support traditional transportlevel security for HTTP and JMS transport protocols
Oneway and twoway certificate based authentication
HTTP basic authentication
Encryption and export of resources (such as service accounts, service key providers,
UDDI registries, SMTP providers, and JNDI providers) that contain user names and
passwords
Service accounts and service key providers to define the user name, password, and
credential alias binding

Clientspecified custom authentication credentials for both transportlevel and message
level inbound requests
() ()
()
1.6.2 Service Bus Service Security Model
A Service Bus service can be secured by security policies that apply to messages in its
interface. A security policy can be specified for a service or for individual messages
associated with the operations of a service. When a security policy is specified for a
service, the policy applies to all messages sent to that service.
You can secure Service Bus services using the following types of security:
Inbound security
Outbound security
Options for identity propagation
Administrative security
Supported standards and security providers
Figure 14 (GUID2CFA406F66DF44F1894BCFD7EC66CEB1.htm#GUID98B671A442984E179362

()
1.6.3 Oracle Web Services Manager
You can secure your Service Bus services by attaching Oracle Web Services Manager
(OWSM) policies. OWSM is a component of Oracle Enterprise Manager Fusion
Middleware Control, a runtime framework that provides centralized management and
governance of Oracle SOA Suite environments and applications. It provides capabilities to
build, enforce, run, and monitor web service policies, such as security, reliable messaging,
MTOM, and addressing policies. OWSM can be used by developers at design time and by
system administrators in production environments. OWSM allows for policydriven
centralized management of web services with local enforcement. OWSM provides a policy
framework to manage and secure web services consistently across your organization.
()
()
1.6.4 Oracle Platform Security Services
Oracle Platform Security Services (OPSS) provides a standardsbased, portable,
integrated, enterprisegrade security framework for Java Standard Edition (Java SE) and
Java Enterprise Edition (Java EE) applications. OPSS provides an abstraction layer in the
form of standardsbased APIs that insulate developers from security and identity
management implementation details. Developers do not need to know the details of
cryptographic key management or interfaces with user repositories and other identity
management infrastructures.
()
()
1.6.5 WSPolicies

Through OWSM, Service Bus security supports the Web Services Policy (WSPolicy)
specification, a standardsbased framework for defining a web service's security
constraints and requirements using policies, each of which contains one or more
assertions. WSPolicy assertions specify a web service's requirements for digital
signatures and encryption, along with the security algorithms and authentication
mechanisms that it requires.
You can include WSPolicy policies directly in a WSDL document or include them by
reference. A WSDL document can import other WSDL documents that contain or refer to
WSPolicy policies. The runtime environment recognizes both abstract and concrete WS
Policy statements. Abstract WSPolicy statements do not specify security tokens.
Concrete WSPolicy statements specify the security tokens for authentication, encryption,
and digital signatures. The Service Bus runtime environment determines which security
token types an abstract policy will accept.
For more information on WSPolicy specification, see the Web Services Policy Framework
(WSPolicy) and Web Services Policy Attachment (WSPolicyAttachment) which is
available at http://specs.xmlsoap.org/ws/2004/09/policy/
(http://specs.xmlsoap.org/ws/2004/09/policy/).

1.6.6 Types of Security
The following sections discuss the security features available in the Service Bus security
model.

()
()
1.6.6.1 Inbound Security
Inbound security ensures that proxy services handle only the requests that come from
authorized clients, and that no unauthorized user has viewed or modified the data sent
from the client. For outwardfacing proxy services, which receive requests from service
consumers, strict security requirements such as twoway SSL over HTTPS are used. If a
proxy service uses public key infrastructure (PKI) technology for digital signatures,
encryption, or SSL authentication, you can create a service key provider to provide private
keys paired with certificates.
()
()
1.6.6.2 Outbound Security

Outbound security secures communication between a proxy service and a business
service. Most of the tasks involve configuring proxy services to comply with the transport
level or messagelevel security requirements that business services specify. If a business
service requires SSL authentication or PKI technology for digital signatures, a service key
provider is required, which provides private keys paired with certificates.
()
()
1.6.6.3 Identity Propagation
The options provided by Service Bus for identity propagation allow for decision making
when designing security, including how to propagate the identities that clients provide.
Service Bus can be configured to authenticate the credentials provided by clients, perform
authorization checks, pass credentials through as is, and map credentials.
()
()
1.6.6.4 User Management and Administrative Security
Service Bus user management is based on WebLogic Server security, which supports
tasklevel authorization based on security policies associated with roles assigned to
named groups or individual users. You use Fusion Middleware Control and the Oracle
WebLogic Server Administration Console to manage Service Bus users, groups, and
roles.
To give users access to functions, such as creating proxy services and other resources,
you assign them to one or more of the predefined security roles with predefined access
privileges. The access privileges for the Service Bus administrative security roles cannot
be changed but the conditions under which a user or group is in one of the roles can be
changed. By default, the first user created for an Service Bus domain is WebLogic Server
administrator. This user has full access to all Service Bus objects and functions, and can
execute user management tasks to provide controlled access to Service Bus functions.
For more information, see "Defining Access Security for Oracle Service Bus
(../../osb/administer/GUIDF6E57B1FE1A345059204DDC8681A3D3E.htm#OSBAG1176)" in
Administering Oracle Service Bus.
()
()
1.6.6.5 TransportLevel Security
Service Bus supports transportlevel confidentiality, message integrity, and client
authentication for oneway requests or request/response transactions over HTTPS.
HTTP(S) proxy services or business services can be configured to require basic
authentication, client certificate (twoway SSL) authentication, custom authentication, or
no client authentication at all. Transport security for transports other than HTTP is
supported in Service Bus as follows:
For the email and FTP transports, security is provided using credentials to connect to a
FTP or email server.
For the file transport, security is provided using a login control to the machine on which
the files are located.
()
()
1.6.6.6 MessageLevel Security

Service Bus supports OASIS Web Services Security (WSS) 1.0. WSS defines a
framework for message confidentiality, integrity, and sender authentication for SOAP
messages. Using WSS, Service Bus provides support for securing messages using digital
signatures, encryption, or both. Though it is not a substitute for transportlevel security,
WSS is ideal for endtoend message confidentiality and integrity. WSS is more flexible
than SSL since individual parts of the SOAP envelope can be signed, encrypted or both,
while other parts are neither signed nor encrypted. This is a powerful feature when
combined with the ability of Service Bus to make routing decisions and perform
transformations on the data based on the message content. Service Bus supports WSS
over HTTP(S) and JMS.
For more information on the WSS specification, see the OASIS Web Services Security TC
which is available at
http://www.oasisopen.org/committees/tc_home.php?wg_abbrev=wss
(http://www.oasisopen.org/committees/tc_home.php?wg_abbrev=wss).
()
()
1.6.7 Custom Security Credentials
Service Bus supports clientspecified custom authentication credentials for both transport
level and messagelevel inbound requests. The custom authentication credentials can be
in the form of tokens, or a user name and password token combination. Service Bus
accepts and attempts to authenticate the following:
A custom token passed to a proxy service in an HTTP header, SOAP header (for
SOAPbased proxy services) or in the payload (for nonSOAP proxy services).
A user name and password token passed in a SOAP header (for SOAP based proxy
services), or in the payload for nonSOAP proxy services.
For outbound requests, custom authentication is supported at the transportlevel based on
a custom authenticator Java class you create. The custom authentication mechanisms
work alone or in concert with the messagelevel security for web services. For more
information on custom security credentials, see Configuring Custom Authentication (GUID
966DBF19BFAD47558F5AD2CD12D9A933.htm#GUID966DBF19BFAD47558F5AD2CD12D9A933)..

1.7 Approaches for Designing Service
Bus Services
When creating Service Bus services, you have a choice of approaches, depending on
whether you use the Oracle Service Bus Console or JDeveloper. JDeveloper supports
both approaches; the console supports the bottomup approach.
TopDown: With this approach, you analyze your processes and identify activities in
support of this process. You create a Service Bus application and project, and define
the Service Bus components through the Service Bus Overview Editor.
BottomUp: With this approach, you analyze existing applications and assets to identify
those that can be used as services. As you create a Service Bus application, you build
the services on an asneeded basis. This approach works well when IT must react to a
change.

() ()
()
1.7.1 Service Bus TopDown Roadmap
With this approach to developing Service Bus services, you can create all your primary
components at one time using the Service Bus Overview Editor. This includes proxy and
business services, pipelines, splitjoins, and JCA adapters. The editor simplifies the
creation and configuration of project components, and provides a graphic view of the
overall structure of the data flow. Once you create and wire these components, you can
define the configuration options for each, and define message routing and transformation
in pipelines and splitjoins.
The following table outlines the steps and provides links for further information.

1.7.2 Service Bus BottomUp Roadmap
With this approach to developing Service Bus services, you create and configure each
project component individually. The flow of messages through the system is defined by
references you create between project components, such as proxy services, business
services, pipelines, splitjoins. This approach does not use the Service Bus Overview
Editor, so you are not working with a graphical representation of the components.
However, if you are working in JDeveloper, the components you create are added to the
overview file and appear in the Service Bus Overview Editor.

1.9.5 Notes About Viewing Service Bus Resources
in a Web Browser
You can also retrieve WSDL documents containing Oracle Web Services Manager policies
so the policies conform to supported WSPolicy and WSSecurity Policy standards. For
more information, see Advertising WSDL Files to Support WS Standards (GUID1CE01E95
8B9B4369AAC928F4C5B6EF63.htm#GUID7B51BC341E32493F85D4D0FD3172F60F)..
If you use special characters in your resource names, the URLs used to expose the
resources in Service Bus must be encoded in UTF8 in order to escape special
characters.

1.10.1 Setting Accessibility Options in JDeveloper
JDeveloper provides accessibility options, such as support for screen readers, screen
magnifiers, and standard shortcut keys for keyboard navigation. You can also customize
JDeveloper for better readability, including the size and color of fonts and the color and
shape of objects. For information and instructions on configuring accessibility in
JDeveloper, see "Oracle JDeveloper Accessibility Information
(http://www.oracle.com/pls/topic/lookup?ctx=fmw121300&id=OJDUG118)" in Developing Applications
with Oracle JDeveloper.

1.10.2 Notes on Screen Reader Mode
When you log in to the Oracle Service Bus Console with the screen reader mode enabled,
selecting the context menus from the Project Navigator requires extra steps. To access
the context menus for projects and components in the Project Navigator, navigate to the
component using the Tab key, press Enter to select the component, and then press
Ctrl+Alt+M to launch the menu. Use the up and down arrows to navigate the options in
the menu.

1.10.3 How to Set Accessibility Options in the Oracle
Service Bus Console
Accessibility settings help you read all components of the application. You can set
accessibility options in the Oracle Service Bus Console for the current instance only. The
console presents the Accessibility menu on the login page, so you can configure
accessibility before you log in.
To set accessibility options:
1. Launch the Oracle Service Bus Console.
2. On the login page, click Accessibility in the top right corner.
The Edit Accessibility Settings page appears, as shown below.
