No, the stacktrace does not show a reference to workflow-ejb.jar, even in the un-truncated version. I tried changing the java2ParentDelegation property to false and, as expected, that did not work. I also tried removing that tag completely and that did not work either. I tried deploying my ear, starting JBoss, and bringing up the JMX console. I clicked on jboss.deployment, then scrolled down to the SubDeployment "vfszip:/home/jhsingl/pkg/jboss-5.0.0.GA/server/default/deploy/workflow.ear/workflow-ejb-2.7.0.jar" and observed the following
