这是test例子的源码

flex端得

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">    
<mx:Script>    	
    <![CDATA[    		
    import mx.controls.Alert;    		
    import mx.rpc.events.ResultEvent;    		
    private function clickLocal():void{    			
        httpLocal.send();    		
    }    		
    private function local_result(event:ResultEvent):void{    			
        var str:String = event.result.name as String;    			
        Alert.show("show local result :"+str);    		
    }    		
    private function clickRemote():void{    			
        httpRemote.send();    		
    }    		
    private function remote_result(event:ResultEvent):void{    			
        var str:String = event.result.name as String;    			
        Alert.show("show remote result:"+str);    		
    }    			    	
    ]]>    
</mx:Script>    
<mx:HTTPService id="httpLocal" url="http://localhost:8080/xuexiao/test.action"     	method="post" result="local_result(event)" />    
<mx:HTTPService id="httpRemote" url="http://211.82.193.188:8080/xuanhua/test.action"        method="post" result="remote_result(event)" />	
<mx:Button x="75" y="61" label="sendtoLocal" click="clickLocal()" />	
<mx:Button x="75" y="136" label="sendtoRemote" click="clickRemote()" />	</mx:Application>

 

   action没做处理，通过jsp页面输出

<?xml version="1.0" encoding="utf-8" ?>

       <name>tiantian</name>

在地址为188的服务端 tomcat 的root目录下添加crossdomain.xml

 

  <?xml version="1.0" encoding="UTF-8"?>

       
<cross-domain-policy>           
<allow-access-from domain="*" />       
</cross-domain-policy>

重启tomcat 即可

测试结果： 点击remote按钮  会弹出alert（“tiantian”）
