This is left as an exercise for the app. server vendor. JOnAS does
not provide any sort of load balancing on a single named bean (in your
example having accounting beans on multiple machines with the client
using the machine with the lowest load) but many commercial EJB vendors
(BEA WebLogic, IBM WebSphere, etc.) do provide this capability.

No, this is not correct. The situation is EXACTLY the same as your situation
is in your MSF framework. The client to server method call needs to be
large grained. But once you are in the server method (be it a session bean
or entity bean) you can employ your naturally fine grained object model.
You don't make fine grained method calls on your MSF workspace from your
client now, right? Just use the same model with your beans and you won't
have any problems.
Later,
Sean
