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

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.
