HI, I suggest check this KB http://support.openview.hp.com/selfsolve/document/KM214626 to configure the EJB Detector.
We have a protocolo in LR11.5x to record this application (that I think you are using):
Protocol Program Supported Version Supported Server
Enterprise Java Beans (EJB) Java 1.4 SUN J2EE SDK
1.5 BEA WebLogic 8.1
1.6.x IBM WebSphere 5.X
I suggest check the KB information to check if the Detector was well configured.
Rodolfo.
