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