RPC, RMI and CORBA

Server Side: Important Detail—Java• In Java, all classes inherit from Object and arerequired to support Object’s core operations• remote objects need special implementations ofequals(), hashCode() and toString(), since thenormal implementations would require remotereferences but don’t throw RemoteExceptions• for remote objects, equals() and hashCode() operate onthe remote object identifier so equality and identityare the same• The required implementations are provided inUnicastRemoteObject. Either extend that class, orprovide reasonable implementations for these threemethods.
