Quartz

Applications can vary from the largest e-commerce system to the smallest stand-alone application.

Quartz can be used to create simple or complex schedules for executing tens, hundreds, or even tens-of-thousands of jobs; jobs whose tasks are defined as standard Java components or EJBs.

The Quartz Scheduler includes many enterprise-class features, such as JTA transactions and clustering.
