I having problem using configuring Quartz MBean. Specifically having problem with JBoss Class Loading. Enviorment: OS: Linux (Ubuntu 7.10) Jboss: 4.0.4 GA Java: 1.5 I have very simple ear with following content: | myapp.ear | |--------- META-INF | | |------------- application.xml (reference modules some.jar and other.jar) | | |------------- jboss-app.xml (reference to service archive myquartz.sar) | | | |--------- some.jar | | |------------- my.test.SomeJob1 (Does not use any external class) | | |------------- my.test.SomeJob2 (references/uses my.test.OtherBean) | | | |--------- other.jar | | |------------- my.test.OtherBean | | | |--------- myquartz.sar | |--------- META-INF | |------------- jboss-service.xml (initialize Quartz MBean) | If i use only my.test.SomeJob1 which does not reference any external class then everything works great. (Quartz Scheduler is properly started and jobs get trigger properly too) But if i use my.test.SomeJob2 which uses an external class in Other.jar(in the same ear) It throws following ClassLoader complain it can not find my.test.OtherBean. | [main] - 01/14/2008 09:09:55 [QuartzService] ERROR: org.quartz.SchedulerConfigException: Failure occured during job recovery.

Does any one have any suggestion to resolve this issue? i have been searching for the solution for good time now. pike View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4119659#...
