Resolves 'name' into a target context with remaining name. It only resolves the hostname/port number. The remaining name contains the rest of the name found in the URL. For example, with a iiop URL "iiop://localhost:900/rest/of/name", this method resolves "iiop://localhost:900/" to the "NameService" context on for the ORB at 'localhost' on port 900, and returns as the remaining name "rest/of/name".
