[jboss-user] [Installation, Configuration & DEPLOYMENT] - MBean configuration - ClassLoader issue

[tprime]

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.

Why can Jboss find the the my.test.OtherBean? Does any one have any suggestion to resolve this issue?

i have been searching for the solution for good time now.
