당신에게 : 마지막 줄 registry.rebind(remoteObjName, stub);에,이 예외의 원인이 무엇

remoteObjName = "blabla"; 
final objectInterface engine = new object(); 
final Remote stub = UnicastRemoteObject.exportObject(engine, 0); 
final Registry registry = LocateRegistry.getRegistry(); 
registry.rebind(remoteObjName, stub);//this line causes the exception.
