首先，我们在eclipse中创建一个web project 取名为simple

在这个project中我们创建一个servlet:代码如下:

package com.test;
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 TestServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("");
out.println("");
out.println("");
out.println("pubDate11111");
out.println("title111");
out.println("description111");
out.println("");
out.println("");
out.println("pubDate222");
out.println("title22");
out.println("description122211");
out.println("");
out.println("");
}
}

这个servlet的访问地址为:http://localhost:8080/simple/test，
现在我们在flex buider3中创建一个flex project,选择web root为tomcat/webapps下面，取名test.
新建一个connect.mxml文件代码如下：

"1.0" encoding="utf-8"?>
"http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="feedRequest.send()">
"feedRequest" url="http://localhost:8080/simple/test"
useProxy="false">
"10" y="10" width="800" height="400" layout="absolute" horizontalAlign="right"
>
"20" y="20" id="dgPosts" width="400" verticalCenter="center" dataProvider="{feedRequest.lastResult.rss.xml}">
"标题" dataField="title" />
"时间" dataField="pubDate"/>
"20" y="175" width="400" height="100" htmlText="{dgPosts.selectedItem.description}"/>

好了！访问一下：http://localhost:8080/test/bin-debug/connect.html
