Can someone help me with this. On page 513 HFEJB, the first BANG box says : Only ststeful session beans can implement SessionSynchronization, because stateless session beans are allowed to maintain a transaction once a method has ended.(means BMT). The Second BANG box says : SessionSynchronization is for CMT beans only. Is this a trick or something ?
By the way, assuming it is a mistake on page 513, why stateless session beans are allowed to implement SessionSynchronization ? Please help me.
Dear Jamie, I think you mis read the statement.On page 513 it says stateless session Bean can't implement Session Synchronization because it is not allowed to maintain transaction once the method has ended. the only difference between a CMT stateless and Stateful bean is when you specify at DD. so even if a bean which implement Session synchronization and is a stateless. I think container will not call those method. which are in SessionSynchronization for a stateless bean. vikas prasad SCJP1.4 SCWCD1.4 SCBCD1.3
