What I'm trying to archive is a setup like this:

1. Client call WebService
2. WebService calls ESB using ServiceInvoker
3. ServiceInvoker calls ESB Service
4. ESB Service starts JBPM process
6. JBPM process does all the orchestration and calls several ESB services on they way. ESB services fill the message with relevant data. After the process is completed/ended call should return to webservice which should be waiting in deliverSync.
7. Webservice has a replyMessage from serviceInvoker.deliverSync with the data in it
8. WebService gets the data from replyMessage and returns it to the Client.
9. Client is happy with the data

The problem is there that I don't know how to configure (or can't get it to work) the ESB service to "hang" until the process has completed and return the data to the caller. What happens is that the JBPM process starts and starts it's own life and the esb service continues its action pipeline until the call is returned to the Webservice.

I think this could be done with ServiceInvoker and confguring the JBPM startup with property reply-to-originator=true.

I'll keep digging around.

Thanks for the fix in SVN.
I got my example working, but I'm still little suspicious.
The only way to get a response back from the JBPM was to set mep="OneWay".
If mep="RequestResponse" the actionpipeline would return before the JBPM process
got it's job done, thus returning a message without the datta to the client.

Is this working as intended?

Client code:

RequestMessage requestMessage = MessageFactory.getInstance().getMessage(MessageType.JBOSS_XML);
// fill requestMessage with data
Message reply = invoker.deliverSync(requestMessage, 70000000);
