在flex中和webservice是很简单，使用Webservice类就好了。
先说一下他的使用呀
???web=new WebService();
//这是一个webservice的地址;
??? web.wsdl = "http://www.webservicex.net/globalweather.asmx?wsdl";? ?
???web.loadWSDL();
这样就已经连接上了.
想监控连接是否成功可以注册LoadEvent.LOAD事件
???web.addEventListener(LoadEvent.LOAD,OnLoad);
下来就可以调用webservice的接口了,激动的时刻来了,如果接口有返回值的话,要先监听一下结果
?
???web.GetCitiesByCountry.addEventListener(ResultEvent.RESULT,OnGetCity);
???web.GetCitiesByCountry("china");
??private function OnGetCity(event:ResultEvent ):void{
???var xml:XML=new XML(event.result);
??}
?
这样就可以了,很简单吧.
