I only posted because I didn't see any other responses at the time. I wouldn't have said a word if I had seen that first response; the author obviously has a much better handle on it than I do.

I guess I misread your first post.

The stop button will call another jsp that will retreive the object stored under that key and call the "stop" method.
I don't accept change; I don't deserve to live.

Sorry. It's explained (better, although still not perfectly) in the next post.

The stop method should interupt this thread and perform and needed cleanup.

NEVER use Thread.stop(). It's extremely dangerous and will more likely than not cause very nasty things to happen.
It's deprecated for a reason you know, and that reason is that it will NOT do any cleanup.
It will kill the thread, and everything in it, now. No questions asked.
If that leaves data in an incomplete or unstable state, it doesn't care. If it leaves network or database resources open it couldn't care less. If it keeps hardware locked, waiting for commands that never can come no more, it's oblivious of that.

of course including any such method in a JSP (which the kid was asking for) is as bad as calling Thread.stop()...
It's likely going to be ineffective as well, as the thread may well survive the context in which the JSP is executed.

that's a different problem, and one you can't solve.
The server will time out the request, and even if not the client will at some point time out the request.
