Actually, you should distribute the business delegate, the remote interface
and the home interface with each client. The business delegate is designed
to act as a local proxy for the remote EJB. This is the main motivation of
the pattern. If you placed the business delegate on the server, not only
would you be defeating the point of the pattern but the code would not work
because the business delegate does not support RMI and so cannot be used
remotely from the client.

Are you talknig about businness delegate design pattern? AFAIK, you put
businness delegate in front of your businness components, the ejb components
in your case. I think it�s more clear to put your businness delegate in the
same environment that your ejb�s are.
Imagine that your ejb components will be called now from a swing application
and not from a web client. You will not distribute your businness delegate
component with each client that will access your businness components, ok?
