Agree with all you say, except use of a session bean to wrap a collection
of entities. Why not push the wrapping further back and use an entity bean
to wrap a collection of java classes? Performance will go way up (EJB->EJB
calls are expensive), and there will be no possibility for accessing any
interfaces other than the "dumbed-down" ones.
