flex_02 java 和 flex 通信

?

这个demo 是flex 和 java 结合使用的,即新建一个flex 项目,再添加web支持,目录如下

四个文件 :

①fx.mxml

? <?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
????? xmlns:s="library://ns.adobe.com/flex/spark"

?<fx:Declarations>
??<!-- 将非可视元素（例如服务、值对象）放在此处 -->
??<mx:RemoteObject id="remoteob" destination="helloword" endpoint="http://localhost/fx/messagebroker/amf" result="resultHandler(event)" fault="faultHandler(event)">
???
??</mx:RemoteObject>
?</fx:Declarations>
?<fx:Script>
??<![CDATA[
???import mx.controls.Alert;
???import mx.rpc.events.FaultEvent;
???import mx.rpc.events.ResultEvent;
???
???private function resultHandler(event:ResultEvent):void{
????Alert.show(event.result.toString(),"成功!");
???}
???private function faultHandler(event:FaultEvent):void{
????Alert.show(event.fault.toString(),"失败!");
???}
??]]>
?</fx:Script>
?
?<s:Button? label="发送" click="remoteob.sayHi()" x="300" y="200"/>
</s:Application>

②HelloWord.java

package com.java;

public class HelloWord {
?public String sayHi(){
??return "hello kitty !!!";
?}
}

③remoting-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service"
??? class="flex.messaging.services.RemotingService">

??? <adapters>
??????? <adapter-definition id="java-object" class="flex.messaging.services.remoting.adapters.JavaAdapter" default="true"/>

??? </default-channels>
?<destination id="helloword" >
????????? <properties>
?????????? <source>com.java.HelloWord</source>
????????? </properties>
??? </destination>
</service>

④web.xml

注:fx.mxml 还可以修改为:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
????? xmlns:s="library://ns.adobe.com/flex/spark"
????? xmlns:mx="library://ns.adobe.com/flex/mx"
????? minWidth="955" minHeight="600">

?<fx:Script>
??<![CDATA[

???{

????var myva :String = myname.text;
????StuServices.addEventListener(FaultEvent.FAULT,faultHandler);
????StuServices.addEventListener(ResultEvent.RESULT,resultHandler);
????StuServices.sayHI(myva);
???}
???
???protected function resultHandler(event:ResultEvent):void
???{
