代码部分按照个人习惯做微量改动，原作者莫怪，呵呵！

如下图所示新建工程：



代码如下：

RomoteTest.java

package client;

import java.net.MalformedURLException;

import server.Hello;

import com.caucho.hessian.client.HessianProxyFactory;

public class RomoteTest {

public static void main(String[] args) {

String url = "http://localhost:8080/Hessian/hessianService";
HessianProxyFactory factory = new HessianProxyFactory();
try {
Hello hello = (Hello) factory.create(Hello.class, url);
System.out.println(hello.hello("kingtoon"));
} catch (MalformedURLException e) {
e.printStackTrace();
}
}
}

HelloImpl.java

package server.impl;

import server.Hello;

public class HelloImpl implements Hello {

public String hello(String name) {

return "hello, " + name + "! Welcome to use Hessian.";
}
}

Hello.java

package server;

public interface Hello {

String hello(String name);
}

所需jar包：本文使用hessian-3.2.1.jar，仅此而已。
