Yep,
The idea of using a session bean facade to your entity beans is to do your work in
batch to prevent multiple remote
calls. So for the example below, you could have a method in the session bean (
doAllThreeMethods() ) that would take
care of all three actions for you.
This holds true for any client of an EJB. Even if the client is another EJB, depending
on your app server, it may not
optimize the calls to local even though it knows it is in the same VM.

Isn't the servlet an ejb client in the same sense that a java app is
an ejb client? Would a java app ejb client have the same issue?
