While the URL does cover issues with isolating classes in Ears and Web Apps, this is "neither" of that type of application.
My application is merely a collection of Timer MBeans that perform routine JDBC calls.
Thus, they are deployed as a jboss-service archive (sar).
Thank you for the link, but it still does not address the issue of how to isolate classes in a SAR.
Any other people out there to help?
How do I turn off the Unified Class Loader for a SAR?
This configuration even works with SARs. Just look into jboss-service_3_2.dtd .
Works for me ;-)
