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.
Contains simple / light-weight implementations (with no dependencies on
external libraries) of interfaces required by the
org.quartz.core.QuartzScheduler.
Contains Service Provider Interfaces that can be implemented by those
wishing to create and use custom versions of Quartz back-end/behind-the-scenes
services.
