If you CREATE the object reference from a string via a CORBA 2.0 compliant library then the object reference is an IOR. If you create the object reference via resolve_initial_references() the ORB libraries might create an OR or an IOR. Some ORBS from companies such as Expersoft and Visigenic ORBs support only native IIOP and thus all references are IORs. On the other hand, some commericial vendors who shipped ORBS that supported IDL before IIOP existed pass around references that are not IORs and thus these referencesmight not always be IORs. Many CASES an ORB vendor might support a proprietary protocol in addition to IIOP. Note: even if resolve_initial_references() returns and IOR, the IOR almost always refers to an object implemented with the same ORB environment as the application calling resolve_initial_references(). If the object reference is obtained from a server, a NameContext, or from a factory, the process and ORB libraries that originially created the object reference, determine if the reference is an OR or an IOR.
