org.apache.ode.bpel.iapi.MyRoleMessageExchange.invoke()
"Invoke" a process hosted by the BPEL engine. The state of the invocation may be obtained by a call to the {@link MessageExchange#getStatus()}method. It is possible that the response for the operation is not immediately available (i.e the call to {@link #invoke(Message)} willreturn before a response is available). In such cases, {@link MessageExchange#getStatus()} == {@link Status#ASYNC} and theintegration layer will receive an asynchronous notification from the BPEL engine via the {@link MessageExchangeContext#onAsyncReply(MyRoleMessageExchange)} whenthe response become available.

                        new QName("http://tuscany.apache.org/implementation/bpel/example/helloworld.wsdl", "HelloService"), "hello");


                Message request = mex.createMessage(new QName("", ""));
                request.setMessage(DOMUtils.stringToDOM("<message><TestPart><hello xmlns=\"http://tuscany.apache.org/implementation/bpel/example/helloworld.wsdl\">Hello</hello></TestPart></message>"));
