無法啓動RMI服務器它

Question

已停止後，我在重新啓動我的RMI註冊表中的一個問題：

import java.rmi.*; 
import java.rmi.registry.*; 
import java.rmi.server.UnicastRemoteObject; 
import javax.swing.JOptionPane; 

public class CinemaServer 
{ 
    private Registry registry; 
    ClientImpl clientImple; //remote interface implemented class 
    private static String title="Cinema Pvt Ltd"; 

    public CinemaServer() { 
     try { 
      clientImple = new ClientImpl(); 
      registry=LocateRegistry.createRegistry(3311); 
      registry.rebind("RMI_INSTANCE", clientImple); 
    } catch (RemoteException e) { 
      JOptionPane.showMessageDialog(null, "Can't Start RMI Server",title,JOptionPane.ERROR_MESSAGE); 
     } 
    } 

    public void stopServer() 
    { 
     try { 
      registry.unbind("RMI_INSTANCE"); 
      UnicastRemoteObject.unexportObject(clientImple, true); 
     } catch (NotBoundException e) { 
      JOptionPane.showMessageDialog(null, "Can't Stop Server",title,JOptionPane.ERROR_MESSAGE); 
     } 
    } 
} 

1. 我啓動服務器：CinemaServer ser=new CinemaServer();

2. 當我撥打ser.stopServer();時，它停止。

3. 但我不能重新啓動它

我越來越：

java.rmi.server.ExportException: internal error: ObjID already in use 
at sun.rmi.transport.ObjectTable.putTarget(Unknown Source) 
at sun.rmi.transport.Transport.exportObject(Unknown Source) 
at sun.rmi.transport.tcp.TCPTransport.exportObject(Unknown Source) 
at sun.rmi.transport.tcp.TCPEndpoint.exportObject(Unknown Source) 
at sun.rmi.transport.LiveRef.exportObject(Unknown Source) 
...

呼叫在createRegistry()失敗，上再出口的對象不是。不要創建註冊表兩次。
