How to use WSO2 ESB to transform text messages into SOAP payloads via JMS

Question

I am using WSO2 ESB to listen on an MQ queue via JMS and then transform a received multi-lines text message into multiple SOAP requests, but unable to make it work without errors.

Error: TID: [0] [ESB] [2014-09-03 13:17:29,198] ERROR {org.apache.axis2.engine.AxisEngine} - The endpoint reference (EPR) for the Operation not found is and the WSA Action = null. If this EPR was previously reachable, please contact the server administrator. {org.apache.axis2.engine.AxisEngine} org.apache.axis2.AxisFault: The endpoint reference (EPR) for the Operation not found is and the WSA Action = null. If this EPR was previously reachable, please contact the server administrator. at org.apache.axis2.engine.DispatchPhase.checkPostConditions(DispatchPhase.java:102)

Here is my proxy configuration for reference:

Please help on what I have not done correctly in this case. Many thanks in advance!

Answer 1

You may need to define the document type after translation, but before the . To do this, you can assign the ContentType axis2 property:

<property name="ContentType" value="application/xml" scope="axis2"/>

If that doesn't work, attaching a full stack dump or a wso2carbon.log would help me troubleshoot it.

Thanks, Colin
