I get java.lang.ClassNotFoundException when invoking EJB from MBean

Solution In Progress - Updated -

Issue

  • When invoking an EJB from an MBean via the JMX Console it fails with the error shown below. This works in JBoss EAP 4.x but in JBoss EAP 5.x/6.x fails.
  • Why do I need to set the TCCL when calling an EJB from an MBean?
  • How can I set the correct classloader for EJB's being called from an MBean?
