Why doesn't

CreateException

rollback the transaction?

Because

javax.ejb.CreateException

is an application exception. It extends

java.lang.Exception

. The container only rollsback for "system" exceptions. i.e. those that extend

java.rmi.RemoteException

,

java.lang.RuntimeException

(like

javax.ejb.EJBException

) and

java.lang.Error

.

See the ejb spec for more information.
