Method and apparatus for RMI-IIOP implementation using Java serialization as a data encoding mechanism. Embodiments may provide a mechanism to use Java serialization rather than, or as an alternative to, CORBA Common Data Representation (CDR), for the marshaling and unmarshaling of data in RMI-IIOP message exchanges. In one embodiment, a server-side Object Request Broker (ORB) may be configured to support the encoding of data in RMI-IIOP messages in accordance with CDR encoding and Java serialization encoding. A client-side ORB may optionally use Java serialization or CDR as the data encoding format for RMI-IIOP messages to invoke the associated object on the server. Response messages from the server to the client may include data encoded according to Java serialization or CDR.
