I'm playing around with Sun's Petstore demo (v1.1.2, an old version so I can apply the JBoss patch) on JBoss 3.0.4. Everything works fine, I can log in, and I've updated it to run on Postgres instead of Cloudscape.
However, when I take the EAR, explode it, and deploy the exploded version, I get several errors like the following:
12:45:32,540 INFO [EJBDeployer]
Bean : TheCart
Method : public abstract ShoppingCart create() throws RemoteException, CreateException
Section: 7.10.6
Warning: The return type for a create(...) method must be the session bean's remote interface type.

Anyone have any thoughts? I see a few posts that comment on different behaviour between exploded and packaged deployments, but nothing conclusive.
