using AS or
<mx:WebService> tag
For
<mx:WebService> tag, specify
id,
url of the wsdl file and optionally fault handler function. You can trap an event called
load that fires when WSDL loads successfully
You can use methods on a Web Service in three ways:
1.Undeclared Method: Use WS with id. Flex looks at WSDL for the method based on how it is called
2.Declared Method: Operations defined as children of WS tag using
<mx:operation> tag. Args validated using WSDL
3.Fully Declared Method: Both operations and arguments declared using
<mx:operation> and
<mx:request> tag.
Declaring operations enables specifying event handlers for each operation
<mx:WebService id="myWebservice" wsdl="http://myWsdlUrl/myWsdlFile.wsdl" fault= handleFaultFunc(event)> <mx:operation name="funcNameInWsdl" result="resultHandlingFunc(event)"> <mx:request> <paramName1InWsdl> {asVar1ToPickInputFrom} </paramName1InWsdl> <paramName2InWsdl> {asVar2ToPickInputFrom} </paramName2InWsdl> </mx:request> </mx:operation></mx:WebService>Then to call the operation
myWebservice.funcNameInWsdl.send();To do in AS:
var myWebservice:WebService = new WebService();myWebservice.wsdl = "http://myWsdlUrl/myWsdlFile.wsdl";ws.loadWSDL(); /*Before calling any method we need to load wsdl. Use canLoadWSDL() to check if WSDL was loaded or not*/ws.addEventListener("result", resultHandlingFunc);ws.addEventListener("fault", handleFaultFunc);ws.funcNameInWsdl(asVar1ToPickInputFrom, asVar2ToPickInputFrom);
