RMI IIOP

From Sun's website:

RMI over IIOP is part of Java2 Standard Edition. RMI over IIOP provides the ability to write CORBA applications for the Java platform without learning CORBA Interface Definition Language (IDL). 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. Use the rmic compiler with the -iiop option to generate IIOP stub and tie classes, rather than Java Remote Messaging Protocol (JRMP) stub and skeleton classes.
