To shutdown / destroy a scheduler, simply call one of the shutdown(..) methods.
Once you have shutdown a scheduler, it cannot be restarted (as threads and other resources are permanently destroyed). Also see the suspend method if you wish to simply pause the scheduler for a while.
//shutdown() does not return until executing Jobs complete execution scheduler.shutdown(true);
//shutdown() returns immediately, but executing Jobs continue running to completion scheduler.shutdown(); //or scheduler.shutdown(false);
If you are using the
org.quartz.ee.servlet.QuartzInitializerListener to fire up a scheduler in your servlet container, its
contextDestroyed() method will shutdown the scheduler when your application is undeployed or the application server shuts down (unless its shutdown-on-unload property has been explicitly set to false).
