Validating a soap request in mule
- 1. Validating a SOAP Request in Mule
- 2. We often come across SOAP web services in our project and often face different challenges in handling SOAP web services. One such challenge is SOAP request validation. .
- 3. In Mule ESB we can expose a SOAP webservices and can handle the request validation in very simple way. .
- 4. Yes, I am talking about using message filter to validate a SOAP request against a given XSD file In simple words if we have the XSD file of web service we can validate the request of the web service against that XSD using a schema validation filter in Mule..
- 5. Let’s see how… Let consider we have a SOAP webs ervice exposed in Mule by following way :-
- 6. Now, if we want to validate the request with an XSD file of the web service and want to throw a custom message in case if the SOAP request is invalid or incorrect, we need to use schema validation filter
- 7. So after adding schema validation filter in our flow, our flow looks like the following
- 8. We can also add a subflow which will throw custom message if the SOAP request is invalid as follow :-
- 9. So, if we test the webservice with a wrong SOAP request in SoapUI we will get a custom message :-
- 10. This is how the flow works:-
- 11. <mulexml:schema-validation-filter name="Schema_Validation" schemaLocations="MainData.xsd" returnResult="true" doc:name="Schema Validation" /> The code:- You need to use schema validation filter which will refer to your XSD files for validating a SOAP request as follows:- The Schema Validation Filter uses the JAXP libraries to validate a message against a schema. You must provide the path, file name, and extension of the schema or schemas in the Schema Locations property.
- 12. <flow name="ServiceFlow" doc:name="ServiceFlow"> <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8082" path="mainData" doc:name="HTTP"/> <message-filter onUnaccepted="ValidationFailFlow" doc:name="filter to validate xml against xsd" throwOnUnaccepted="true" > <filter ref="Schema_Validation"/> </message-filter> <cxf:jaxws-service validationEnabled="true" serviceClass="com.test.services.schema.maindata.v1.MainData" doc:name="SOAP"/> <component class="com.test.services.schema.maindata.v1.Impl.MainDataImpl" doc:name="JavaMain_ServiceImpl"/> </flow> A code snipped of the Mule config:-
