I think if we don't add @Local to the interface , that interface is a local interface by default.
So, I think :
option 3

the developer can add @Local to either of the local interface ...

and
option 6

only add@Remote ... no need to do anything for the local interface

Without @Local in the interface, that interface is local by default.

As per section 4.9.7 - If a bean class has more than one interface—excluding the interfaces listed below—any business interface of the bean class must be explicitly designated as a business interface of the bean by means of the Local or Remote annotation on the bean class or interface or in the deployment descriptor.

Hi admin,
So, if the bean class only implement one interface and that interface does not have @Local annotation, that interface is a local interface by default.

But if the bean class implements multiple interfaces and the interfaces don't have @Local annotation, then the bean provider has to explicitly annotate @Local/@Remote.

Correct me if I am wrong.
