I am trying to call a webservice from my Flex application and this is the code:

 <mx:WebService id="myWebService"
     wsdl="http://172.16.111.103:22222/cics/services/PRESENT1?wsdl">

     <mx:operation name="PRESENT1Operation"
          result="resultHandler(event)"
          fault="faultHandler(event)">
    </mx:operation>
 </mx:WebService>

//Function to send customer id to the wsdl request

 private function searchDetails():void{
            myWebService.PRESENT1Operation.send(cusNo.text);
            cusDetails.visible=true;
        }

The webservice is up and running. I have a separate Java application to test the webservice, And I am able to execute it properly. I am able to request the webservice and get response.

But If I try to call the webservice through the Flex application, I get the following error.

 [RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Unable to load WSDL. If currently online, please verify the URI and/or format of the WSDL (http://172.16.111.103:22222/cics/services/PRESENT1?WSDL)"]
