Hi all,
I had one question to ask regarding web services in flex 2.Actually i
trying to switch from XFire to Axis2.However, my flex client's codes
work well when using XFire and it will hit an error when i trying to
use Axis2.The error is as shown in the following:-
TypeError: Error #1009: Cannot access a property or method of a null
object reference.

My flex client's snippet code:
...
_ws = new WebService();
_ws.addEventListener(LoadEvent.LOAD, wsdlLoadedHandler);
_ws.loadWSDL("http://localhost:8080/testWebServices/services/TestWebServices?wsdl";);
...
private function wsdlLoadedHandler(event:LoadEvent):void
{
var operation:Operation = _ws["getBase64String"];
operation.resultFormat = "e4x";
operation.addEventListener(ResultEvent.RESULT, resultHandler);
operation.addEventListener(FaultEvent.FAULT, faultHandler);
var test:String = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
operation.send.apply(this, [test]); ---->> error occurs
}
Do anyone have an idea on what's happening? Thanks
