Note: This release of the JavaTM 2 Platform, Standard Edition, includes RMI-IIOP, a technology that integrates Java RMI (Remote Method Invocation) and Java IDL. RMI-IIOP supersedes Java IDL for most purposes, by enabling you to write CORBA-compliant interfaces directly in Java rather than in the OMG-specified IDL (interface definition language) used with Java IDL. For details, see the RMI-IIOP documentation. Also note that Java IDL now uses a new version of the Java-to-IDL compiler. This compiler supports new CORBA-standard features required for RMI-IIOP. The compiler is supplied with this release of the Java SDK, and is placed in the SDK's .bin directory by the installer.
For better interoperability, see the note about not using an interface name for a module name in OMG IDL code.
Java IDL adds CORBA (Common Object Request Broker Architecture) capability to the Java platform, providing standards-based interoperability and connectivity. Java IDL enables distributed Web-enabled Java applications to transparently invoke operations on remote network services using the industry standard OMG IDL (Object Management Group Interface Definition Language) and IIOP (Internet Inter-ORB Protocol) defined by the Object Management Group. Runtime components include a fully-compliant Java ORB for distributed computing using IIOP communication.
