Plz any on help JSP chat program........

no. That's not the way to use JSP so we're not going to help you do it.
We're not going to do what you want anyway, which is to give you a fully working application.

Do your own research, and your own work. It's been done a million times (at least) before so there's no reason any reasonably intelligent person shouldn't be able to figure it out.
