# Java RMI over IIOP

> Java Remote Method Invocation over Internet Inter-ORB Protocol technology ("RMI-IIOP") is part of the Java Platform, Standard Edition (Java SE). The RMI Programming Model enables the programming of CORBA servers and applications via the `rmi` API. You can choose to work completely within the Java programming language using the Java Remote Method Protocol (JRMP) as the transport, or work with other CORBA-compliant programming languages using the Internet InterORB Protocol (IIOP).

> RMI-IIOP utilizes the Java CORBA Object Request Broker (ORB) and IIOP, so you can write all of your code in the Java programming language, and use the `rmic` compiler to generate the code necessary for connecting your applications via the Internet InterORB Protocol (IIOP) to others written in any CORBA-compliant language. To work with CORBA applications in other languages, IDL can be generated from Java programming language interfaces using the `rmic` compiler with the `-idl` option. To generate IIOP stubs and tie classes, use the `rmic` compiler with the `-iiop` option.

## More Information

> See the Java RMI over IIOP Technology Home Page.

> The Java IDL technology pages include a lot of information that is useful to developers using Java RMI-IIOP technology.

> The OMG is the official source of information for all CORBA and IIOP related information. The CORBA 2.3.1 Specification is available electronically from formal/99-10-07. The URLs for the CORBA specifications may change. If this link is broken, link to http://www.omg.org and search the specifications.

> For more information on which specifications are implemented in this release of the Java platform, see the compliance document.

> For questions, please try the user supported forum for RMI-IIOP technology, which is available at http://forum.java.sun.com.
