EJBException should be thrown in the bean implementation when an error has occured such that the bean is no longer useable. The container is the mark the transaction for rollback, discard the bean instance (ie. NO more business method calls on it) and throw a RemoteException to the client.

Yep. That fixed it.
So any idea who/when an EJBException should be thrown ?
Thanks

Have you tried to remove EJBExceptions from "throws"
