Hi Jim Really thanks for your quick reply. I did read somewhere that said WS-Addressing is utilized here, but for WSDL2, is still? And the main problem is since the external service does not have to implement "callback" logic, so even it got BPEL's EPR, how does it know when is the best time to send reply back?
As soon as you have a callback EPR, you should be able to invoke it. Now whether it works in practice is a question of message exchange pattern and transport layer. Ode queues all messages it receives, so if you have a one-way invocation, or a request-response invocation happening over a connection-less protocol (e.g. JMS) then it should work. The message will be queued and processed when the process reaches the corresponding <receive> activity. For the HTTP protocol, you have to stick to one-way invocations to avoid transport-level timeouts. alex
