True, the browser scenario will be somewhat different (no permanent
TCP connection). Still running a standard IM server in the backend,
interfacing with a custom webapp may be beneficial in many cases - it
provides lots of facilities that you'd otherwise have to write from
scratch (depends on how complex your requirements are of course).
Also regardless of whether you use an IM server or not, check out
Jetty6 continuations - it presumably provides a server push facility
that can be used from AJAX:

I meant to try it in a while to see how far you can go with the
"push" part, but never had enough time to do it.

Hi Andrus.
Thanks for the hint, but I was looking for a chat that runs inside the
browser. If the user has install a client, we could use whatever we
want.
But thanks, it gave me some interesting ideas.

Check out XMPP-based solutions. E.g. http://www.jivesoftware.com/ has
open source Java client (Smack) and server (Wildfire). Just be aware
that the server component is GPL licensed. If this doesn't fit your
needs, you may have to buy commercial license from them for the
server component.

I never used it with WO, but I wrote a Smack-based XMPP client for
Cayenne Remote Object Persistence (aka JavaClient to WO developers).
It enables group "chat" between Cayenne apps, i.e. targeted
notifications of context changes. Pretty cool.
