I haven't done this yet, but eventually I will have to.
My intended solution was to have a single Home/Remote Interface pair and just
provide multiple implementations of the bean class. Each bean would be
registered with a separate name in JNDI and the client would just look up the
version of the bean that it needs. Since they all have the same Home/Remote
Interface pair, the casting would be exactly the same for all implementations.
Is this not the expected way to do this in J2EE?
