Camunda BPM 7.2: Connectors, Data, Scripting (English)
- 1. Hands-on Webinar Camunda BPM 7.2 Connectors, Data, Scripting
- 2. 10+ years experience with workflow and Java EE Co-Founder of Camunda Evangelist and Head of Consulting @berndruecker [email protected] Bernd Rücker
- 4. Our sample process: Supplier Onboarding SOAP WebService Java Delegate Object File E-Mail Template, Connector, & Script Connector Template & Script Data Formats Embedded Form Data Formats Data Formats
- 5. Data Format Support −Serialization of process variables as XML/JSON −Transparent transformation of formats (e.g. POJO -> JSON -> XML) −Allows to use objects in process variables without having byte arrays in the database −Reduces code of process applications Camunda BPM 7.2
- 6. Scripting −Every JSR-223 compliant scripting engine can be used (we tested JS, Groovy, Jython and JRuby) −Scripts can now be used everywhere −Script sources can be externalized (to allow editors / code completion) −Performance was improved (compile & cache) Templates −Template Engines can be registered as script engine (Templates = Scripts) −Freemarker and Velocity provided per default (+ XSLT in the Enterprise Edition) −Makes data transformation really easy −Can be used to build requests for Connectors Camunda BPM 7.2
- 7. Connectors −Reusable Components with I/O-Mapping −Configured via BPMN process model (XML) −Typically used for (synchronous) Service Calls −Out-of-the-box: SOAP and REST (based on Apache HTTP Client) Camunda BPM 7.2
- 8. Where can I use Scripts/Templates? In Script Tasks In Listeners As Conditions As IO- Mappings
- 9. Where can I use Connectors?
- 10. Let‘s dive into the details…
- 11. We use a Java Object of class „CreditorApplication“ Default: Serialize as byte array Possible: Serialize as JSON/XML Process variables Process Engine Process Variable Serialization
- 12. DEMO
- 13. Now let‘s get serious… Build SOAP Request via Freemarker or XSLT Serialized as JSON Use SOAP Connector XPath + Script to set bank in CreditorApp. Use Java Object in Java Delegate Work with JSON in Tasklist / Forms Use EL Transform to XML via SPIN Custom File Connector Groovy Script
- 14. DEMO

- 16. This is AWESOME! And I tell you why :-)
- 17. We have a fundamentally different approach than Zero-Code Suites! It‘s not about „empowering Business Analysts“ We make the developer more productive („Less code“) As not every developer speaks Java we make the platform polyglott We now introduced new use cases Developer Friendlyness Whitepaper by Sandy Kemsley / 2014 http://camunda.com/lan ding/whitepaper- developer-friendly-bpm/
- 18. Building „Zero Code“ Solutions −IT divisions that want to provide a workflow infrastructure for their organization (other IT teams) −Software vendor who wants to make processes customizable in their software Classless Deployments −No Java Code / Classes needed (Re-)deployment during runtime without Java Deployment −Scripts & co can be versioned as part of the process definition (but as well externalized into own files) New Use Cases By the way: You can build own modeler extensions…
- 19. And improved „normal“ Use Cases (real-life example) App Server (JBoss AS 7) Apache httpd + PHP Camunda Engine Process Application REST camunda-webapp PHP-Frontend camunda-bpm-php-sdk* ESB Talend on Karaf SOAP (Apache CXF) * Community Extension
