[jboss-user] [Management, JMX/JBoss] - Quartz MBean cannot find Classloader

[davidn]

Hi,

Loading a deploy/quartz-service.xml works quite nicely upon startup, but if there is a class in the Quartz Job table, the MBean-launched service can't find the classloader. I attempted to resolve it with a  element, but after reading for hours, there are no clear answers. There are some posts that skirt the issue, but no best practice or practical replies.

Following is the descriptor, then the error:
