Uses of Class org.omg.CORBA.ORB (Java Platform SE 8 )
Date: 2026-03-16

## Uses of Class
org.omg.CORBA.ORB

- Packages that use ORB
  Package | Description
  --- | ---
  javax.rmi.CORBA | Contains portability APIs for RMI-IIOP.
  org.omg.CORBA | Provides the mapping of the OMG CORBA APIs to the JavaTM programming language, including the class `ORB`, which is implemented so that a programmer can use it as a fully-functional Object Request Broker (ORB).
  org.omg.CORBA_2_3 | The CORBA_2_3 package defines additions to existing CORBA interfaces in the Java[tm] Standard Edition 6. These changes occurred in recent revisions to the CORBA API defined by the OMG. The new methods were added to interfaces derived from the corresponding interfaces in the CORBA package. This provides backward compatibility and avoids breaking the JCK tests.
  org.omg.CORBA.portable | Provides a portability layer, that is, a set of ORB APIs that makes it possible for code generated by one vendor to run on another vendor's ORB.
  org.omg.CosNaming | Provides a naming service for Java IDL.
  org.omg.PortableServer | Provides classes and interfaces for making the server side of your applications portable across multivendor ORBs.
  org.omg.PortableServer.portable | Provides classes and interfaces for making the server side of your applications portable across multivendor ORBs.
