You can not throw CreateException in ebjCreate() methods of MDB , session bean and entity bean.the mothods its name begin with "ejb" invoked by container,container does expect get application exception such as CreateException .But you can throw CreateException in Create() methods of session bean and entity bean home interface, but not MDB.beasause MDB have not client, if you throw one, who will receive it.(MDB have not Home interface and component interface.)

Hi Si
CreateExceptions are allowed to be thrown from ejbCreate methods of session and entity beans but not from MDB beans. See EJB Spec Pg 96 7.10.3.

Also spec section 15.7.3 page 324 - you aren't supposed to even declare any application exception on the ejbCreate for an MDB.
