1. I do not see the problem with derived bean remote interface extending
base bean remote interface.
2. I also do not see the problem with derived bean class extending base
bean class.
3. The only serious problem with inheritance support in EJB 1.1 I see is
that finder method in base class currently cannot return instances of
derived class because there are now way for finder method to tell right
type for bean. And I do not see how dynamic aggregation solves this
problem. Could you please explain your idea?
