java.lang.Objectweblogic.rmi.extensions.PortableRemoteObject
public final class PortableRemoteObject
API for managing references required by higher-level
functionality. In particular we need to be able to narrow to IDL
interfaces and create initial references. These functions mirror
those in PortableRemoteObject
but guarantee that
the WebLogic versions will be called since users can replace
the implementation of PortableRemoteObject
themselves.
