我在停止RMI注册表后重新启动它时遇到了问题:
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);
}
}
}
我使用以下命令启动服务器:
CinemaServer ser=new CinemaServer();
当我调用
ser.stopServer();
时,它会停止。但是我无法重新启动它
我得到的错误信息为:
java.rmi.server.ExportException: internal error: ObjID already in use

调用替换为e.printStackTrace()
,并复制您在控制台上得到的内容。 - Paŭlo Ebermann
