I understand that since the bean is stateless the beans instance may not be
the same for two invocations on the same objref. But I am wondering whether
the EJBObject will be diffrent as well. I read that the bean instance may
get swapped for the same EJBObject instance.
And also I am planning to take the objref in the client side and let
multiple threads use it. I am pretty sure that this thing will bomb in case
of stateful sssion bean -- but whether the same will happen for stateless is
the question.
cheers

Need not, because the bean above is stateless.

The objRef (the register object) is a remote stub. I'm not sure if it has
been stated in the spec, but the objRef need not be thread-safe.
In effect, the association between the objRef and and instance is dynamic,
and is managed by the container.
