That's what I've read and from the code it's the default. I'm hacking together a listener that rolls the entire chain from scratch rather than depending on the Quartz-supplied listener. I'll add some debugging logging and see what happens.
I might also try just creating the SchedulerFactory first, then getting a scheduler, then starting the scheduler, and finally adding a job. ----- Original Message ---- From: Pid <p...@pidster.com> To: Tomcat Users List <users@tomcat.apache.org> Sent: Mon, October 18, 2010 3:15:28 PM Subject: Re: Tomcat memory leak error launching web app in NetBeans 6.9.1 On 18/10/2010 23:02, Mark Thomas wrote: > On 18/10/2010 16:56, Mark Thomas wrote: >> On 18/10/2010 12:05, Mark Eggers wrote: >>> I saw a mention of this on the Quartz forums.

Calling scheduler.shutdown(true); /should/ cause it to block & wait for existing jobs to finish. The Quartz supplied Listener does appear to do this: http://svn.terracotta.org/fisheye/browse/Quartz/trunk/quartz/src/main/java/org/quartz/ee/servlet/QuartzInitializerListener.java?r=HEAD p --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
