Ben! Wah! Great! Could you give me more information about your implementation? I am not clear with iFrame.

The frame just points to a servlet which queries the database for new messages. If there is a new message, the iframe uses javascript to fire off a pop up. message. You're other option would be to use an applet that maintains a statefull connection to your server. A applet list would be a better place to discuss that approach though.
