He showed component inheritance. Yes, component inheritance is not
supported. It is one of things that are being considered for EJB2.0
(AFAIK anyway).

The problem is with finders. You will find it impossible to implement
component inheritance properly without the help from the EJB-container.
It's not something you can just add "on top".
