flex调用servlet

我想用flex调用servlet中的doget方法，请大家帮忙看一下哪里有问题~多谢
servlet端：

package com.abc.servlet;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class Test1 extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

System.out.println("已经调用servlet");
}


public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {


}

}


Flex端：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" 
layout="absolute" 
creationComplete="service.send()">

<mx:HTTPService id="service" 
url="http://localhost:8080/test1/com.abc.servlet/Test1.do"
method="GET" />  
  <mx:Script>  
  <!--[CDATA[  
  private function send():void{  
  //发送请求
