What is Quartz Quartz is a full-featured, open source job scheduling system

that can be integrated with, or used along side virtually any J2EE or J2SE application - from the smallest stand-alone application to the largest e-commerce system.

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.
