我得到這個奇怪的錯誤，當我運行我的簡單的CORBA服務器（這是我建跟隨這tutorial0org.omg.CORBA.Object上的錯誤objRef = orb.resolve_initial_references（「NameService」）;
這裏是我的代碼：
import org.omg.CORBA.ORB;
import org.omg.CORBA.ORBPackage.InvalidName;
import org.omg.CosNaming.NameComponent;
import org.omg.CosNaming.NamingContextExt;
import org.omg.CosNaming.NamingContextExtHelper;
import org.omg.CosNaming.NamingContextPackage.CannotProceed;
import org.omg.CosNaming.NamingContextPackage.NotFound;
import org.omg.PortableServer.POA;
import org.omg.PortableServer.POAHelper;
import org.omg.PortableServer.POAManagerPackage.AdapterInactive;
import org.omg.PortableServer.POAPackage.ServantNotActive;
import org.omg.PortableServer.POAPackage.WrongPolicy;
import HotelServer.Hotel;
import HotelServer.HotelHelper;
import HotelServer.HotelImpl;
public class StartServers {
public static void main(String[] args) throws AdapterInactive, InvalidName, ServantNotActive, WrongPolicy, NotFound, CannotProceed, org.omg.CosNaming.NamingContextPackage.InvalidName {
// create and initialize the ORB //// get reference to rootpoa & activate the POAManager
ORB orb = ORB.init(args, null);
POA rootpoa = POAHelper.narrow(orb.resolve_initial_references("RootPOA"));
rootpoa.the_POAManager().activate();
HotelImpl hotel = new HotelImpl();
hotel.setOrb(orb);
// get object reference from the servant
org.omg.CORBA.Object ref = rootpoa.servant_to_reference(hotel);
Hotel hotelref = HotelHelper.narrow(ref);
org.omg.CORBA.Object objRef = orb.resolve_initial_references("NameService");
NamingContextExt ncRef = NamingContextExtHelper.narrow(objRef);
NameComponent path[] = ncRef.to_name("hotel1");
ncRef.rebind(path, hotelref);
orb.run();
System.out.println("ORB Server is running...");
}
}
錯誤發生在這一行：org.omg.CORBA.Object objRef = orb.resolve_initial_references("NameService");
以下是完整的錯誤：
