java IM

hi i was wondering how to create a java Instant Messenger at the bottom of my web page such as on Myspace.com And Facebook.com .
Thanks,
Nick

I think that'd be easier to do with scripting, but it's very possible with Java. Try Googling Servlets (server side) and Applets (client side).

You have to love the questions on this forum sometimes, now this is a rather wide question. If you wish to use Java I'd suggest writing this as a servlet and then have an AJAX call poll the servlet for new posts every so often.

You could of course look into Reverse AJAX as well if thats something you'd like to achieve.
