consumir web service NET desde actionscript

[gualicho]

Hola gente que tal. Bueno les comento mi tema:
Soy desarrollador C#, estoy empezando una web, y he decidido usar flex en el lado cliente, y C# de backend. La intercomunicacion seria a traves de webservices. El tema es el siguiente, flex, al crear el objeto WebService, me pide el "uri", que segun creo es la direccion del wsdl, que vendria a ser: "http://localhost/web/servicio.asmx?wsdl" no? o bien "http://tempuri.org/operacion"? Tengo una confusion con eso, porque el servicio todavia no lo tengo alojado en la web, sino localmente, y pienso que si pongo "play" (debug) en el visual studio, me carga el webservice, y creo que deberia estar disponible para accederlo, sin embargo, en actionscript me tira la excepcion de que no encuentra el wsdl... probe con tempuri, localhost, etc pero no hay caso.
Alguno hizo esto o sabe de alguna paginola con algun ejemplo copado? ya que no hay mucho sobre flex 2 todavia... y si bien la documentacion es bastante completa, no es la sintaxis de flex lo que me frena sino algun problema de configuracion seguramente.

Saludos y muchas gracias.

Este es un buen sitio para comenzar

Hola Meister, bueno gracias, estuve ya leyendo esa documentacion, pero por eso, creo que mi problema pasa por otro lado, ya que mi problema es el bendito "path not found" cuando quiero cargar el wsdl... no es sobre la sintaxis de flex.

Si alguien hizo esto algunas vez por favor digame.
Gracias, saludos.

Oks.

Bien. lo que puedes hacer es comprobar si realmente tu localhost regresa algo. puedes usar el Tag de MXML traceTarget que es un Debugger detallado de todo lo que pasa en tu aplicacion algo asi.

Código HTML:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
	<mx:Script>
		<![CDATA[
			import mx.events.*
			private function onResultOK(event:Event):void
			{
				trace(event)
			}
			private function onResultFault(fault:Event):void
			{
				trace(fault)
			}
		]]>
	</mx:Script>
	<mx:TraceTarget />
	<mx:WebService wsdl="http://localhost:port/path/to/your/file.wsdl" id="miConexion">
	    <mx:operation result="onResultOK(event)" fault="onResultFault(event)" name="Handler"/>
	</mx:WebService>
</mx:Application> 

No olvides correr tu aplicacion en modo Debug

Saludos!!

A ver aqui te dejo un Ejemplo comsumiendo un webService real

Código HTML:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" applicationComplete="init()">
	<mx:Script>
		<![CDATA[
			import mx.events.*
			import flash.xml.*
			public function init():void
			{
				miConexion.GetQuote.send()
			}
			public function onResultOK(event:Event):void
			{
				var data:XMLDocument = new XMLDocument();
				data.parseXML(miConexion.GetQuote.lastResult);
				trace("********************************************")
				trace("****** El Servicio Regresa *****************")
				trace(data.firstChild.firstChild.firstChild.firstChild)
				trace("********************************************")
			}
			public function onResultFault(fault:Event):void
			{
				trace(fault)
			}
		]]>
	</mx:Script>
	<mx:TraceTarget />
	<mx:WebService  wsdl="http://www.swanandmokashi.com/HomePage/WebServices/QuoteOfTheDay.asmx?WSDL" id="miConexion">
	    <mx:operation name="GetQuote" result="onResultOK(event)" fault="onResultFault(event)" resultFormat="xml" makeObjectsBindable="true"/>
	</mx:WebService>
</mx:Application> 

En la consola de Debug veras algo asi:
