文档：
接口调用：
接口类型 Hessian
请求Url http://kaifu.5173.com/MobileKfInfo.hessian
接口定义：
方法名称返回值类型       返回值说明
GetMobileAdData 字符串 Json数组格式的字符串
方法名称返回值类型返回值说明
GetMobileKfData 字符串 Json数组格式的字符串
接口参数:
参数名/类型
pageIndex/整数
pageSize/整数

以下是我根据百度一些教程写的代码：
package hessian;

public interface Basic {

      String Hello(String name);

      String GetMobileAdData();

      String GetMobileKfData(int pageIndex, int pageSize);
}

//用来给客户端调用的提供服务的接口

package hessian;

public class basicservice implements Basic {

public String Hello(String name) {
// TODO Auto-generated method stub
return "Hello";
}

public String GetMobileAdData() {
// TODO Auto-generated method stub
return "Hello";
}

public String GetMobileKfData(int pageIndex, int pageSize) {
// TODO Auto-generated method stub
return "Hello:"+pageIndex+pageSize;
}

}
//实现该接口的功能

package hessian.test.client;

import java.net.MalformedURLException;

import com.caucho.hessian.client.HessianProxyFactory;

import hessian.Basic;

public class HessianClient {

   public static void main(String[] args) throws MalformedURLException {

String url = "http://kaifu.5173.com/MobileKfInfo.hessian";
HessianProxyFactory factory = new HessianProxyFactory();
Basic basic = (Basic) factory.create(Basic.class, url);
System.out.println("Hello:"+  basic.Hello(url));
System.out.println("Hello:"+  basic.GetMobileAdData());

}
}

//HessianClient客户端

但是运行之后报错，没有返回内容。。报错如下：
Exception in thread "main" com.caucho.hessian.client.HessianRuntimeException: com.caucho.hessian.io.HessianProtocolException: '6' is an unknown class definition
