While it is expected that the bean class will typically implement its business interface(s), if the bean class uses annotations or the deployment descriptor to designate its business interface(s), it is not required that the bean class also be specified as implementing the interface(s).
does this mean if in bean class,
we are exposing the buisness interface using the @Local annotation. Then there is no need for MyBean to implement the MyBeanInterface.
@Stateless
public class MyBean{
@Local(MyBeanInterface.class)
}
