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. Stubs and other code, generated either from IDL or interfaces written in the Java programming language, can call into these ORB APIs.

# CORBA Features Throwing NO_IMPLEMENT() Exceptions

Some methods throw NO_IMPLEMENT() exceptions by default, but ORB vendors can override them to provide real implementations. The ORB included in Sun's release of the Java[tm] Platform, Standard Edition 6, includes implementations for the following methods.
