Need to Study EJB2.0 for EJB3.0 ?

[Amit Suresh Pawar]

Hi,

I want to know that , as EJB3.0 added more features to EJB, so we need to study EJB2.0 thoroughly?

Or the EJB3.0 with added features is enough...........

Thank You..........

No. But at least know how to use an EJB3 bean from an EJB2 bean, and vice versa.
