[Asterisk-java-users] xmpp integration

[g f <gf...@gm...>]

Hello all,
I was interested in incorporating xmpp  into my asterisk-java web app.
Any recommendations from *-java users that have successfully integrated
xmpp?
My requirement would be conference rooms and voice chat ability and the
embedding of the client into a web app.
Libraries? Clients?, ???
Thanks all!
