Parameters:

proxy - an instance of our own proxy

Returns:

the underlying EJB instance associated with the proxy

needsBeanLocalViewAddedToTypes

public boolean needsBeanLocalViewAddedToTypes()

Returns:

true if the bean supports a no-interface (bean-class) local view but the container does not return it in the list of business local interfaces.
