The problem is that these are commented out. The remote and local
business interface processing is based on the bean class, not any
super-classes. The same goes for the component-defining annotations,
@RemoteHome, @LocalHome, type-level @Interceptors. There is
no support for "session bean inheritance" so many of the things that
define the structural behavior of the bean are limited to being declared
on the bean class itself or ejb-jar.xml. As in prior versions of EJB,
inheritance is allowed from the bean class, but only as implementation
inheritance.
