flex部署到tomcat，远程访问无法与java交互的问题

首先，flex与java交互有很多种方法，我用的是blazeds，这个问题主要还是

endpoint="***",一定不要写localhost，必须是真实IP地址

另外，不要在myeclipse里装载项目，一定要导出发行版，然后外部启动tomcat，最后还要记得沙箱安全奥！

<mx:RemoteObject destination="hello" id="h"

result="gg(event)"

endpoint="http://localhost:8080/flexweb/messagebroker/amf" >

</mx:RemoteObject>

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:分别用代码实现了三种flex4与Java通信

        三种方式:

                       1 flex 与普通java类通信RemoteObject

                       2 flex 与服务器交互HTTPService

                       3 flex与webservice交互WebService

        1 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 SimpleService {




    public String sayHello(String name){


        return "Hello, "+name;


    }


}



        配置说明:配置remoting-config.xml


<destination id="myservice">


        <properties>


            <source>com.flex.demo.SimpleService</source>


        </properties>


    </destination>
        调用


<!--flex 与普通java类通信-->


        <s:RemoteObject id="serv" destination="myservice" fault="serv_faultHandler(event)" result="serv_resultHandler(event)">


            


        </s:RemoteObject>
        2flex 与服务器交互HTTPService

        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.HttpServletResponse;




/**


 * 功能描述:该servlet用来与flex进行交互


 * @author Administrator


 *


 */


@SuppressWarnings("serial")


public class SimpleServiceServlet extends HttpServlet {


    


    @Override


    protected void service(HttpServletRequest request, HttpServletResponse response)


            throws ServletException, IOException {


        request.setCharacterEncoding("utf-8");


        response.setCharacterEncoding("utf-8");


        response.getWriter().write("我是服务器");


    }


}



        调用


<!-- flex 与服务器交互-->


        <s:HTTPService id="service" fault="service_faultHandler(event)" result="service_resultHandler(event)" url="http://localhost:8080/flexdemo/simpleServiceServlet">


            


        </s:HTTPService>
        3flex与webservice交互WebService


<!--flex与webservice交互这里调用一个天气预报的webservice-->


        <s:WebService id="ws" 


                      wsdl="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl" 


                      fault="ws_faultHandler(event)" 


                      result="ws_resultHandler(event)" 


                      showBusyCursor="true">


            <!-- 第二种调用webservice的方法<s:operation>-->


            <!-- <s:operation name="getWeatherbyCityName"> webservice中的方法名-->


            <s:operation name="getWeatherbyCityName">


                <!--传递的参数-->


                <s:request>


                    <!--参数名称必须与webservice中定义的参数名一致否则调用不成功报错-->


                    <theCityName>


                        {city.text}


                    </theCityName>


                </s:request>


            </s:operation>


            


        </s:WebService>

        初次接触flex的朋友,看上面的肯定很迷惑,因此这里录制了视频教程,视频的质量是蛮好的,该视频从头至尾演示了flex4整合Java的过程.为了方便在windows平台下播放,该视频默认导出格式为exe,在此说明该文件并非病毒,实乃视频文件,大家可放心观看.点我下载flex4与Java交互演示视频
