本文介绍了一个使用Java RMI实现的简单远程接口示例，包括接口定义、实现类及服务器启动过程。通过此示例，读者可以了解如何创建并部署RMI服务。

interface:

package rmi;

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

public interface PerfectTimeI extends Remote {

public abstract String getHelloWorld(String name) throws RemoteException;
}

impl:

package rmi.impl;

import java.rmi.RemoteException;

import rmi.PerfectTimeI;

public class PerfectTimeImpl implements PerfectTimeI {

public String getHelloWorld(String name) throws RemoteException
{
return name+", hello world!";
}
}

server:

package server;

import java.rmi.RMISecurityManager;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
import java.rmi.server.UnicastRemoteObject;

import rmi.PerfectTimeI;
import rmi.impl.PerfectTimeImpl;

public class Start_rmi {

public static void main(String args[]) {
System.out.println("////////////////");
System.setSecurityManager(new RMISecurityManager());
try {
PerfectTimeImpl pt = new PerfectTimeImpl();
PerfectTimeI per = (PerfectTimeI) UnicastRemoteObject.exportObject(
pt, 0);
Registry registry = LocateRegistry.getRegistry();
registry.bind("PerfectTimeI_lookup", per);
System.out.println("-----Ready to do time ");
} catch (Exception e) {
System.out.println(e.getLocalizedMessage());
e.printStackTrace();
}
}
}
