Foil 10 EJB Component Types - I

From Object Web Computing Technologies CPS714 Computational Science Information Track -- June 16 99. by H. Timucin Ozdemir
EJB defines three types of components:
  • stateless
  • conversational
  • persistent
Stateless components refer to services that do not require any previous state information (Stateless Session Bean).
Conversational components refer to object that maintain their state across multiple client method invocations and it finishes off as soon as client finishes with the client (Stateful Session Bean).
