main.mxml:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="332" height="198" creationComplete="WS.sayHelloWorld('abc').send()">
 <mx:Script>
  <![CDATA[
   import mx.controls.Alert;
  ]]>
 </mx:Script>
  
  
 <mx:Panel x="0" y="0" width="331" height="200" layout="absolute">
  <mx:DataGrid x="4.5" y="0">
   <mx:columns>
    <mx:DataGridColumn headerText="用户编号" dataField="col1"/>
    <mx:DataGridColumn headerText="姓" dataField="col2"/>
    <mx:DataGridColumn headerText="名" dataField="col3"/>
   </mx:columns>
  </mx:DataGrid>
 </mx:Panel>
 
 <mx:WebService id="WS" wsdl="http://localhost:8080/webService/service/HelloWorld?wsdl" fault="Alert.show(event.fault.faultString,'Error')">
  
  <mx:operation name="sayHelloWorld">
   <mx:request>
    <in0>
     aa
    </in0>
   </mx:request>
  </mx:operation>
 </mx:WebService>
</mx:Application>

 

//上面的creationComplete="WS.sayHelloWorld.send()"也可以不带参数，可以写成这样的形式：

 <mx:operation name="sayHelloWorld">
   <mx:request>
    <in0>
     aa
    </in0>
   </mx:request>
  </mx:operation>

 

<mx:operation name="sayHelloWorld" result="wsHandle(event)">

private function wsHandle(e:ResultEvent):void{
    Alert.show(e.result as String);
   }

 

 

<mx:webService>传递参数：

       <mx:operation  name="方法名">

                  <mx:request>

                             <参数名1>值1</参数名1>

 

写成下面的像这样的不行：（元素必须是in0,in1,in2等等）<mx:request>
    <name>aabbcc
    </name>
   </mx:request>

webService见webservice spring xfire的实例
