Hello,
i have the following problem. I hope hier in the remoting forum i can find help. For Background information see the other thread: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=98256
I have a BPEL process invoking my deployed service. The remote service receive the request and process it. It generate a response and send (try to send) it back to the running bpel BPEL process. Wright know the connection with the invoker is losed see:

But the generated SOAP Message (Response) are well received by the Jbossws components org.jboss.remoting.transport.http.HTTPClientInvoker
and org.jboss.ws.soap.MessageFactoryImp:
Response Message of remote Host:

| <validCustomerResponse xmlns="urn:samples:schufa">
| <validCustomerReturn>true</validCustomerReturn>
| </validCustomerResponse>
| </soapenv:Body>
| </soapenv:Envelope>
I think hier the running process instance can't access the generated SOAP Response routed and when the jbpm.bpel module try to access the expected SOAP Message (see following Error log) by reading the RPCBody elements in the output elements, the collection object are not initialised and therefore this cause a NullPointerException.

At this point of time i don't know if this issue is related to the use of wrong jbossws bibliotheke instead of axis one and why i can't access the generated SOAP Response within the bpel process after the jbossws create a new message and failed to initialyse his contain by copying his message parts.
Any one has an idee what is wrong hier?
Thanks for any suggestion.
