Hi Mahee, I dont know wht could be the problem ...
better try with Alternatively, you can use the following ColdFusion, PHP, or Java URLs: http://www.coldfusionportal.org/flex3cf/PlainHTTPService.cfm http://examples.adobe.com/flex3/exchangingdata/text/plainHttpService.php http://examples.adobe.com/flex3app/flex3samples/exchangingdata/text/PlainHttpService.jsp Coding explanation for the following part <mx:HTTPService id="xmlRPC" resultFormat="e4x" url=" http://www.flexmonkeys.com/F3GSE/PartII/quickstart/xmlHttpService.aspx"; result="handleXML(event);" fault="handleFault(event);" useProxy="false"> <mx:request xmlns=""> <zipcode>{zipcode.text}</zipcode> <pounds>{weight_lb.text}</pounds> </mx:request> </mx:HTTPService> This above code says you are trying to use a *HttpService *which will use the given url. The result format will be in *e4x* (*E4X* means "ECMAScript For XML") . If the result is success then the method *handleXML(event)* will be triggered. If the redult is failed then *handleFault(event)* will be called , where you can handle the error and give a custom message to the user. the *useProxy *specifies whether to use the Flex proxy service. The default value is false. inside the *<mx:request>* node we will give the parameter values to that services . for this particular service we are giving *zipcode *and *pounds *as parameter Here you can find how this code works.
