force download question

Hi,
I have codes that already create a file on server side. But then, right after the creation, I want to force this file to user's system as download (not opening).
Is there a way to do this in jsp ? Thank you for your help.

See my posts in this thread (http://www.sitepointforums.com/showthread.php?postid=492934) - it should be easy enough to do the same in JSP.

;)

For further help I'm going to move this to the correct forum. :)
