realtime messaging with websphere

smartgwtee-4.0p eval version.


I am trying to integrate RTM with websphere 7. Trying to get the simplechat example the swocase working w. websphere. Am able to show the screen if dont include the following bit in teh client code.




Messaging.subscribe("chatChannel", new MessagingCallback() {
@Override
public void execute(Object data) {
chatLog.setContents(chatLog.getContents() + (String)data);
}
});



If I include this, I get a blank screen..


suspect something in the web.xml? Here is what i have currently:
