Is there a good Open Source Chat Room program out there? Preferably one that is running on JAVA?

Im looking to install (and host) a chat room for my web site.  I would prefer one that runs on JAVA so I can conserve my resources.   Are there any leading Open Source chat room programs?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
