I communicate with the server through RPC, but I wanted to know how to
implement the Observer pattern in GWT.
I wanted to know how the server invokes the method update() on the
client!
I'm doing a chat through Observer I know all the events!
Server-side
public class service implements extends RemoteServiceServlet
implements
Service {
ServerObserver s=new ServerObserver();
....
}
public class ServerObserver extends Observable{
....
}
client side
public class ChatGui extends Panel implements Observer{
.....
public void update(Observable o, Object arg) {
...
}
}
