Hi,
I have made some progress in being able to invoke an entry point, however,
in the code below, the get on the future seems to be timing out on line 7. I
am trying to invoke a transient, synchronous two way process. Is there
anything I am missing. I do have an encompassing JTA transaction. However, I
don't want to commit between the invoke and the get, as the process is part
of a larger transaction.
01: MyRoleMessageExchange mex = bpelEngine.createMessageExchange(uid,
portTypeName, operationName);
02: mex.setProperty("isTwoWay", "true");
03: org.apache.ode.bpel.iapi.Message request = mex.createMessage(new
QName("", ""));
04: Element payload =
odeMessageFactory.fromJaxb(((Object[])message.getBody())[0], operationName);
05: request.setMessage(payload);
06: mex.invoke(request).get();
07: Element response = mex.getResponse().getMessage();
Regards
Meeraj
