Q.) How does Stateful Session Bean store it's client state?

Hi Radhika,

Stateful Session Bean.
The Stateful Session Bean LOGICALLY is a "client thread
with State".This thread can be Activated/Passivated as
per the situation.But during this
activation/passivation essentially the state is saved
plus anything else instructed by the bean developer in
respective methods.
In other words the state mangement control is available to
Bean developer also.

Let me know if i am wrong...

Thanks
Hari

In case of StatefulSessionBean the state of the Object is serialized and stored in memory.When same client makes a request, the state of the statefulsessionbean is deserialized and ready to serve the Client request.
This is done by the way called activation and passivation.
