package rmi;

import java.rmi.Remote;
import java.rmi.RemoteException;

/**

public interface MyRemote extends Remote{

    public String sayHello() throws RemoteException;
}

MyRemote 实现类【MyRemoteImpl.java】

package rmi;

import java.rmi.Naming;
import java.rmi.RemoteException;
import java.rmi.registry.LocateRegistry;
import java.rmi.server.UnicastRemoteObject;

/**

    protected MyRemoteImpl() throws RemoteException {
        super();
    }

    @Override
    public String sayHello() throws RemoteException{
        return "Hello world";
    }

    public static void main(String[] args){
        try {
            MyRemote myRemote = new MyRemoteImpl();
            LocateRegistry.createRegistry(6600);
            Naming.bind("rmi://127.0.0.1:6600/helloworld",myRemote);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

客户端【MyRemoteClient.java】

package rmi;

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

/**

 */
public class MyRemoteClient {

    public MyRemoteClient(){

    }


    public static void main(String[] args) {
        new MyRemoteClient().go();
    }

    private void go(){
        try {
            MyRemote myRemote = (MyRemote)Naming.lookup("rmi://127.0.0.1:6600/helloworld");
            String res = myRemote.sayHello();
            System.out.println(res);
        } catch (NotBoundException e) {
            e.printStackTrace();
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (RemoteException e) {
            e.printStackTrace();
