flex4与Java通信实例

1、flex4与Java交互         flex4出来一段时间了,去年看了一段时间flex3,后来由于暂时没有项目需求.所以flex遗忘了很多.这次使用flex4+myeclipse8.5录制了一个视频.以免时间长了遗忘.        软件环境:windows7+flex4+myeclipse8.5+blazeds        功能描述:分别用代码实现

2、了三种flex4与Java通信        三种方式:                       1 flex 与普通java类通信RemoteObject          

3、             2 flex 与服务器交互HTTPService                       3 flex与webservice交互WebService     &

4、#160;   flex 与普通java类通信RemoteObject       普通Java类:         package com.flex.demo;/* */* * 功能描述:该类用来实现flex与普通java类中的方法通信 * author Administrator * */public class&

5、#160;SimpleService     public String sayHello(String name)        return "Hello, "+name;            配置说明:配置remoting-config.xml<destinatio

6、n id="myservice">        <properties>            <source>com.flex.demo.SimpleService</source>        </properties>

7、0;   </destination>        调用<!-flex 与普通java类通信->        <s:RemoteObject id="serv" destination="myservice" fault="serv_faultHandler(event)"&

8、#160;result="serv_resultHandler(event)">                    </s:RemoteObject>        flex 与服务器交互HTTPService     

9、0;  servlet代码         package com.flex.demo;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.Ht

10、tpServletResponse;/* */* * 功能描述:该servlet用来与flex进行交互 * author Administrator * */SuppressWarnings("serial")public class SimpleServiceServlet extends HttpServlet         Override
