eclipse上的JAVA RMI问题

我试图在eclipse上运行一个简单的Java RMI,但每次都会出现不同的错误。如果我通过CMD运行我的源代码(我在Windows上),它就可以工作,但我更喜欢在Eclipse上运行我的代码,因为它更舒服!

这是代码:

接口

package rmiproject;

import java.rmi.*;

public interface HelloIn extends Remote {

    public String ciao(String name) throws RemoteException;
}

服务器

package rmiproject;

import java.net.MalformedURLException;
import java.rmi.Naming;
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;

public class Server extends UnicastRemoteObject implements HelloIn {

    protected Server() throws RemoteException {
        super();
        // TODO Auto-generated constructor stub
    }

    /**
     * 
     */
    @Override
    public String ciao(String name) throws RemoteException {
        // TODO Auto-generated method stub
        String output= "Server dice ciao "+name;
        return output;
    }

    private static final long serialVersionUID = 1L;

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        System.setProperty("java.rmi.server.hostname","myipaddress");
        try {
            Naming.rebind("//localhost/Server", new Server());
        } catch (RemoteException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

顾客

package rmiproject;

import java.net.MalformedURLException;
import java.rmi.Naming;
import java.rmi.NotBoundException;
import java.rmi.RemoteException;

public class Client {
    private static HelloIn lookup;

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try {
            lookup= (HelloIn) Naming.lookup("//localhost/Server");
            String s= lookup.ciao("peppe");
            System.out.println(s);
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (RemoteException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (NotBoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

这是我在Eclipse上运行它时遇到的错误:

当我在CMD上运行它时,我遵循以下步骤:

• 首先,我为JDK设置了一条路径,然后开始 rmi注册表 .
• 然后我打开另外两个窗口,启动服务器,然后启动客户端。

javac rmiproject/Server.java
java rmiproject.Server

对于不同窗口上的客户端也是如此。
