I'm not talking about the EJB 1.1 specs, but the EJB model where a
finder returns a primary key. The EJB server has no clue which entity
bean type it is, given just the primary key.
How do you get around it? Do you return the primary keys and guess which
type they are, or do you return the actual entity beans from the finder?
