Quartz is a full-featured, open source job scheduling service that can be integrated with, or used along side
virtually any Java EE or Java SE 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 that are
programmed to fulfill the requirements of your application. The Quartz Scheduler includes many
enterprise-class features, such as JTA transactions and clustering.
