The problem is that you are trying to setup your target server to also be your callback server (client.addListener(handler, locator);). If you want "push" callbacks, meaning when callback generated it will be sent at that point in time to the callback listener, will need to create a callback server within the client. Can reference following link to sample callback client that shows how to setup callback for both push and pull callbacks. http://viewcvs.labs.jboss.com/cgi-bin/viewcvs.cgi/JBossRemoting/src/main/...
