Forbidden.

But let's generalize it more:
How can we have singleton objects?

As far as I know only entity beans and JNDI contents are shared,
session beans don't. But entities are persistent. Suppose I want
to have something like a "static activeUsersList" in a bean and act
as a true singleton object, only one instance avialable.
How can I "cleanly" implement it?
