I'm trying to learn how to use the WebService class in ActionScript 3.0 as part of a Flex 2.0 XML tutorial I'm writing for my blog (www.brucephillips.name/blog).
I'm having great difficulty getting the code below to work. I've read throught the RPC components section of the Flex 2 Developer's Guide and the WebServices description in the ActionScript 3.0 Reference. I've also search through FlexCoders and Google. The references are extremely POOR in giving working examples of how to use class WebService. The below code uses the currency exchange rate WebService described here: http://www.xmethods.net (under demo services). I know the WebService works as I've tested it using ColdFusion. Any help you can provide me would be much appreciated and I will mention your assistance in my blog. The problem appears that my resultHandler function is never called as the test in my TextArea component does not change. Here is the code: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute" creationComplete="useWebService()"> <mx:Script> <![CDATA[ import mx.rpc.soap.LoadEvent; import mx.controls.Alert; import mx.rpc.events.ResultEvent; import mx.rpc.events.FaultEvent; import mx.rpc.soap.WebService; public function useWebService():void { var service:WebService = new WebService(); service.wsdl = "http://www.xmethods.net/sd/2001/CurrencyExchangeService.wsdl"; service.getRate.addEventListener("result", resultHandler); service.getRate.addEventListener("fault", faultHandler); service.loadWSDL(); service.getRate("canada", "united states"); } public function resultHandler(event:ResultEvent):void { myTextArea.text = "Result returned"; } public function faultHandler(event:FaultEvent):void { Alert.show("fault: "+ event.toString()); } ]]> </mx:Script> <mx:TextArea x="134" y="65" id="myTextArea" text="getting service"/> </mx:Application> Thanks in advance.
