The failing scenario is: @Stateless class MyBean extends SuperBean implements SomeInterface {} | | interface SomeInterface {} | | class SuperBean implements RemoteInterface {} | | @Remote interface RemoteInterface {} If I follow the letter than SomeInterface will become the only business interface (local). If I follow EJBTHREE-785 than RemoteInterface will become the only business interface (remote). I think we can get away with the following: * If the bean class has no interface (including interfaces from superclasses) explicitly declared as a business interface and the bean class implements a single interface, than that interface is assumed to be the local business interface of the bean.
