I misunderstood your question. I still don't fully understand what you are trying to
accomplish.
Could you send a more specific example using the late binding technique? Perhaps we
can figure out a solution that would work with you within the spec constraints.
Note that we wanted to make the home interface type-safe. Therefore, the create and
finder
methods of the home interface are defined as type-specific, not generic. The other
reason
why we wanted the methods to return the exact type was to avoid the client to perform
the PortableRemoteObject.narrow operation.
