I am trying to create a web service that is based on Java classes.I would like to run code after an acknowledge message has been returned within a Java method. Something like

1. Call a specific operation (method) of my web service
2. Start processing X
3. Send an ack response that the processing has been started
4. Continue processing X

How can I implement something like this?
Thanks in advance

This is called asynchronous processing.  If you google for java and that, you'll find more references.

What you do is pass off the long processing -- the stuff that happens asynchronously -- to a thread which is separate from the web server context.  The web server servlet context responds with "we're working on it" and you send an email or something like that when the asynchronous thread completes processing.

There are other ways to do it, all of them involve having 2 different processing threads or 2 completely different processors, to handle the 2 tasks.

It's also possible to have javascript on a page -- if the soap context is based on a web interface -- tell the user that you're working on it, while the main servlet context continues with the long processing.  Again -- 2 processes for the 2 different tasks.
