session synchronziation

[Praveen Kumar Mathaley]

Hi paul,
Stateful session bean is allowed to implement SessionSynchronization method but Stateless Session bean is not allowed! why?
Stateless session bean can also be a part of transaction , i.e a transaction started by stateful session is propagated to stateless session when a method is called in a transaction or else we can specify to start new transaction everytime a method is called...

that's why it's unclear to me as of why the stateless session bean is not allowed to implement the session synchronization...

thank you in advance...

Stateful Bean can update the state value for integrity,but Stateless Bean has no state need to update.
