Packages that use org.omg.CORBA

Package	Description
com.sun.corba.ee.org.omg.CORBA
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.ContainedPackage
org.omg.CORBA.ContainerPackage
org.omg.CORBA.DynAnyPackage	Provides the exceptions used with the DynAny interface (InvalidValue, Invalid, InvalidSeq, and TypeMismatch).
org.omg.CORBA.InterfaceDefPackage
org.omg.CORBA.ORBPackage	Provides the exception InvalidName, which is thrown by the method ORB.resolve_initial_references and the exception InconsistentTypeCode, which is thrown by the Dynamic Any creation methods in the ORB class.
org.omg.CORBA.TSIdentificationPackage	Provides the exceptions that may be thrown during OTS or JTS registration of call-back interfaces with the ORB.
org.omg.CORBA.TypeCodePackage	Provides the user-defined exceptions BadKind and Bounds, which are thrown by methods in in the class TypeCode.
org.omg.CORBA.ValueDefPackage
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.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.
