I start JBoss and get the following reports by the [Verifier] info below. Note that my app still works fine when passing these args. What I don't understand is MyPK and MyInfo (both return type and args implement Serializable) which makes them legal types for RMI-IIOP. Yet it still reports this.

Any ideas.

[Verifier]
Bean : MyBean
Method : public MyPK ejbCreate(MyInfo) throws CreateException, RemoteException
Section: 9.2.3
Warning: The method arguments of an ejbCreate(...) method must be legal types for RMI/IIOP.

Am I missing/forgetting somethings?
Any help much appreciated.
