Within the EJB3 specs there is a distinction between a business interface and a remote interface (for session beans chapter 4.6.6 vs 4.6.7). A business interface must not extend EJBObject, a remote interface must extend EJBObject. IIOP interoperability only works on remote interfaces (chapter 15), thus they must extend EJBObject. Note: the specs only allow for EJB 2.1 remote client view beans, but with the current implementation no EJBHome is required for stateless and service beans.
