Perhaps it serializes all calls to an entity bean instance. Or perhaps it creates multiple bean instances and lets the transaction capabilities of the database sort it out. > - Stateful Session: ditto concurrent calls aren't allow to session beans (Section 6.5.6 of the spec). The bit about "calls to session bean instances are serialized" I believe refers to container callbacks mixed in with client calls to a session object. hope that helps, david -- David Sims [EMAIL PROTECTED] Sims Computing, Inc. www.simscomputing.com =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff EJB-INTEREST".
