I think the best way to learn this stuff is if you get a good book on EJBs.
I recommend Monson-Haefel's Enterprise EJBs.

Why is the stateless returning the same name? Think about what is
happening.
Client A asks for a NameBean, so WLS puts one in the container and sets and
gets a name
Client A then again dos a get and a set.
These 4 methods COULD go to different instances, but the point of Stateless
session beans
is that the container can share instances, so throughout this process WLS
could share
the same object.
Try a multithreaded client that calls many many methods at the same time and
you will see different behaviour.
So, you think you are seeing the same behaviour as w/ Stateful, but it is
just a sideeffect of your limited test.
