Hi,
I have a struts application that will have to perform a few tasks at
the same time. I'm planning to spawn a separate thread for each task,
but I need to be able to stop each thread at any time and when the
thread is stopped it needs to do a certain amount of clean up.
Can you give me a general idea of how something like this is usually
done?
Can you point me to the resources that describe how to handle this
situation?
Appreciate your help.
Thanks

How about Thread.interrupt(), interrupted() and isInterrupted()?

http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Thread.html#interrupt()
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Thread.html#interrupted()
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Thread.html#isInterrupted()

That way you can also terminate IO operations etc.

Thanks for the reply. I also need to keep track of each thread and
it's status etc.. I need to be able to interrupt a specific thread.
The thread should be constantly pooling for the interrupted status. I
was thinking of creating some thread manager to hold the threads. I'm
sure it's been done before.

I still only got a vague idea of what you are trying to do and what all
the pooling talk is about. Even if you use thread pools you can use
aforementioned methods to interrupt activity (even if you implement a
custom Runnable that does the work).

If you have any other suggestions I'd appreciate it.

ThreadGroups?
