Hi to All.


What is the Difference between statefull and stateless session bean?

[Suseela doddi]

Stateless Session Bean,which doesnt maintain state(conversational state) across method calls
and Stateful Session Bean,which maintains state across method calls.

[Mahendran Aiyappan]

Stateless Session Bean should not have any Instance Variables, where as Stateful Session Bean can have Instance Variables. The Instance Variables is calles a State.

Hi Subbarao,

Stateless session beans don't have any state specific to a client.But they have state in the form of instance variables.

Stateful session beans maintain the client specific state across the method calls with a single client.
