--------------------------------------------------------------
I've defined an MBean whose classes are in a JBoss module (stored at $JBOSS_HOME/modules/ucs/jb4compat/main).  My configuration/standalone.xml lists this module as in global-modules under the ee subsystem. I have an EAR deployment (standalone/deployments/MyEar.ear) which has META-INF/jboss-service.xml that references the MBean in the module.  My EAR starts to deploy, the module class is found, and the start() method of the MBean is called.  All of the attributes listed in the mbean element in jboss-service.xml are called, and my properties are set as expected.  So far so good...

The problem arises in that one of the attributes set via jboss-service.xml::server/mbean/attribute is intended to be the name of an attribute on the classpath.  Under JBoss 4.2.3 (from which I'm migrating), the MBean calls Thread.currentThread().getContextClassLoader().getResource([attributeValue]) which yields a URL to the classpath resource which would usually get something out of EAR/META-INF.  Under JBoss 7.1.1, the TCCL appears to be the JBoss Module (ucs.jb4compat) classloader rather than the EAR's classloader, so I have no access to classpath elements within the ear.

Is there a way within the MBean's start() method that I can get a handle on the classloader of the EAR which contains the jboss-service.xml that spawned the MBean in the first place?  Any help would be appreciated.

Best regards,
Zac Bedell
