Java Rmi 异常

Question

我想建一个RMI服务器，我试过这样

package first_project;

import java.rmi.Naming;
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
import java.util.ArrayList;


public class Server extends UnicastRemoteObject implements ServerInterface {

    // list for know users
    protected ArrayList<ClientInterface> clients = new ArrayList<ClientInterface>();


    public Server() throws RemoteException {}

     //logged in clients get a notification that a new user has joined the chat
     // remote reference to the new client is added to the ArrayList.
    public void login(ClientInterface client, String nickname) throws RemoteException {
        broadcastMessage("--> " + nickname + " is entering the chatroom", "");  
        clients.add(client);
    }

    // used for broadcasting an incoming message
        //  and the nickname of its sender to all currently logged in clients .
        //remote call of the method getMessage which is

    public void broadcastMessage(String message, String nickname) throws RemoteException {
        for (int i = 0; i < clients.size(); i++) {
            ClientInterface c = clients.get(i);
            try {
                c.getMessage(message, nickname);
            } catch (RemoteException e) {

                            logout(c);
                    i = i - 1;
            } }}

        //remove user
    public void logout(ClientInterface client) {
        clients.remove(client);
    }


    public static void main(String[] args) {
        try {
            Naming.rebind("Server", new Server());
            System.out.println("Server is ready");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

但我不知道为什么会出现这个异常：

java.rmi.ConnectException: Connection refused to host: 192.168.1.3; nested exception is:

请问我做错了什么？

您是否启动了注册表。启动注册表后尝试
start rmiregistry for windows
rmiregistry & for Linux/Unix
