Schedule an EJB?

I have an EJB which takes input from JSP, and running stored procedure in the database. Because it will run for a long time, its better to run during some schedule hours.

After user submit a job from the JSP front, the Stateless Session EJB needs to "wait" until 2:00 AM before it runs the task. How can I do that? I don't want to use a loop since it will eat up all system computing resource.

Thanks

Kenny
