API question: Class instantiation with Tomcat

[Luis Andrei Cobo <va...@megapathdsl.net>]

Is it possible to tell a servlet to execute another class on the server to
run independantly from the servlet, for example:

jsp calls a servlet and passes in a request object.

the servlet processes the request, and returns information to the client,
but also initializes a class on the server to run outside of the client
server interaction, perhaps performing some routine database clean up or
something similar, which shouldnt interrupt the flow of the client-server
process.

How is this done?

Yes this is possible,
Have a look at www.coolservlets.com , they havea utility package called
ServletMaintenance.
The idea is that you instantiate in the init() method of a servlet that
class which runs as a thread scheduled to perform
some task every x days/hours/minutes.
The  ServletMaintenance class gives you all the scheduling functionality ,
you only need to overide the method that will be executed and also specify
how often you want it to execute (days/hours/minutes).
