Facebook like Chat App with GWT

[gangurg gangurg]

I am trying to implement a Facebook style Chat APP . I use JBOSS as my APP server . Can anyone share thoughts on how do I go about .

I have GWT for my client .

Hello,
I am also interested in this feature. I've started doing something
with server events that notifies the client when something has
changed...
This could be interesting for you:
de.novanic.eventservice.GWTEventService

I hope this helps. If you improve something, please share it with the
community.

Maybe you should check out the channel API from AppEngine. It works
with web sockets and it´s very easy to use. You should make use of
sockets because the server can notify the client if something new
happened. The client doesn´t have to poll all the time.

Is there any channel API without AppEngine?

Check out ijab. It is based on GWT and look really like the Facebook Chat

I'm currently looking at iJab myself. It doesn't look like there is
any active development. Also, the latest beta has connection issues
on Safari. Check http://code.google.com/p/ijab/issues/detail?id=16

You can use long polling. There is a gwt project:
