I don't recall if there was a question on reentrant on my exam. To be on the safe side I recommend that you know that the only bean type that can be marked as reentrant are entity beans and that you indicate the whether an entity bean is reentrant through the required reentrant subtag of the entity tag in the deployment descriptor.
1. Also by default, all entity beans reentrant property have their
value set to false in the DD.
2. If there is any re-entrant code in session beans, then either
EJBException or RemoteException will be obtained by the client.
