As far as from EJB2.0 spec point of view entity bean can never execute under Bean Managed Transaction, it has to run under Container Managed Transaction. Please look into section 17.3.1.

Hi Vikram, Thanks for the reply, but as you the transaction in Entity Bean B is Bean Managed Transaction and not Container Managed Transaction, as you mention that it all depends on the trans-attribute of the bean, which I assume is the trans-attribute in the deployment descriptor which in Entity Bean B there is none as it is a Bean Managed Transaction Correct me if I'm wrong.
