Thanks Dan.
The idea would be to present one interface to the application programmer,
EJB user,
and yes, using a facade, hide the EJB stuff. I'm trying to figure out how
or if I
would want to use the DynamicProxy object to facilitate the facade.

I don't remember the specific thread you are referring to, but in the
contexts I have seen it discussed, Proxy is an implementation
detail hidden from the client programmer.

When you say application programmer, are you talking about
someone who writes enterprise beans or someone who writes
clients that use enterprise beans?
It seems as though you are talking about the latter, but the client
programmer's burden doesn't seem that great to me. You have an
interface that implements the factory pattern and another that
provides the business logic, and that's pretty much it. (You may
want to hide some details of these in case your client were to use
a different technology.)
Do you have an idea how you would like your client code to look?
It may be possible to present a facade to the EJB stuff to get the
effect you are looking for.
