Remote Method Invocation (RMI) over Internet Inter-Orb Protocol (IIOP) delivers Common Object Request Broker Architecture (CORBA) distributed computing capabilities to the Java 2 platform. RMI over IIOP was developed by Sun and IBM. The joint work by Sun and IBM to implement Object Management Group (OMG) standards demonstrates the spirit of collaboration that continually moves the Java platform forward.
Currently industry is working on developing standards to improve interoperability and determine what the common Object Request Broker (ORB) will be. Developing client/server systems using technologies that support distributed objects holds great promise, as these technologies support interoperability across languages and platforms, as well as enhancing maintainability and adaptability of the system.
Lately there has been much public discussion about Java-based distributed computing. Specifically, developers have asked to clarify what Java technologies they should use for Java-based distributed computing and how these technologies work together. This lead to the development of RMI-IIOP.
