停止RMI服务器后无法启动

萨努：

停止后重新启动RMI注册表时出现问题：

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);
        }
    }
}

我用以下命令启动服务器： CinemaServer ser=new CinemaServer();
当我打电话时，ser.stopServer();它停止了。
但我无法重新启动

我越来越：

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)
...

jtahlborn：

调用失败createRegistry()，而不是重新导出对象。不要两次创建注册表。
