Java Enterprise in a Nutshell, Second Edition

Name

PortableRemoteObject

Synopsis

This is the base class for server objects that support RMI-IIOP. The interface supports exporting a remote object to accept client requests, generating client stubs for a server object, and for safely casting references to remote objects (using the narrow() method), among other things. This interface is important in CORBA and EJB contexts when it is desirable to keep your code portable with respect to both RMI and IIOP remote objects.
