An instance of a stateful session bean
- gets created with create() - this also creates state (invoking create
again, gets you a differnent instance)
- if you keep invoking methods on the bean, you keep accessing the same one
(hence the bean can maintain
state)
- gets destroyed (bean instance and it's state) when you invoke remove() or
when it times out
- gets passivated after a while of inactivity and (re)activated when needed
(ie any method gets
invoked on it)
So in your case, your rendering frontend (JSP/servlet) will have to handle
the user session mgmt
and associate the rights JavaBeans with the right user, and the javabeans
will have to manage the
life cycle of your EJB (stateful session) beans.
