Flex怎么解析，调用WebServer,刚接触不懂！

	<s:WebService id="treeSource" 

				  wsdl="http://61.152.255.108/AccessDeclarationServer/AccessDeclarationService.asmx?wsdl"

				  operations="EventTypeQueXML"

				  useProxy="false"

				  requestTimeout="30" 

				  showBusyCursor="true" 

				  result="result_Hander(event)" 

				  fault="fault_Hander">

		</s:WebService>



或者直接as代码





var ws:mx.rpc.soap.mxml.WebService = new mx.rpc.soap.mxml.WebService();

				ws.showBusyCursor = true;

				ws.wsdl = "http://61.152.255.108/AccessDeclarationServer/AccessDeclarationService.asmx?wsdl";

				//处理成功获取数据

				ws.addEventListener(ResultEvent.RESULT,ResultEventHander);

				//调用失败查看错误信息

				ws.addEventListener(FaultEvent.FAULT,FaultEventHander);

				ws.getOperation("EventTypeQueXML");

				ws.EventTypeQueXML();
