anonymous wrote : I don't remember off hand how that is done in Messaging. The lines | callbackServer = CallbackServerFactory.instance.getCallbackServer(serverLocator); | client.addListener(dummyCallbackHandler, callbackServer.getLocator()); | in JMSRemotingConnection create callbackServer as a server and then tell the server side to call it to do push callbacks. If you were just to call | client.addListener(dummyCallbackHandler); | omitting the creation of callbackServer, you would be configuring for pull callbacks, with no server on the client side.
