Question about EJB 3.0

by cold80@[EMAIL PROTECTED] Feb 7, 2007 at 09:14 AM

Just to understand better...I'm studying EBJ 3.0, session beans,
entities and JBoss to write web and distribuited applications for my
University coruse of Web Architecture. I'm studying a lot of
do***entation and as a reference I'm reading the book "Mastering EJB
4th Edition". The problem is I can't understand the goal of
entities...I mean...am I supposed to use them always in the same VM
that is hosting the sessions beans, my jsp pages and servlets? Because
if I want to develop a client application that use the session beans
in order to interact with the server I need to let the entities
serializable and I have to give the .class files of the entities to
the client too! And this is not very good because if I change these
entities I'm supposed to deploy the new .class files to all the
clients...

I hope I made myself clear

Thanks in advance for your help

Cold
