You have a remote interface and a bean class. How can you make sure
that inheritance happens on both the remote interface "side" and the
bean class "side"? You are correct that on either side you can inherit
as much as you like.
Incidentally, this is a BOF presentation that my colleague David Walend
and I are looking to present at JavaOne next year. There are many
solutions to this problem; we (hopefully) will present one.
