Flex 3 - Import SAP Web Service Error

Hi Experts,

I was trying the example [Quickstart Using Flex and SAP Web Services|https://wiki.sdn.sap.com/wiki/display/EmTech/QuickstartUsingFlexandSAPWebServices] and got stuck while importing the WSDL into Flex.

I followed the steps Data -> Import Web Services (WSDL), here when I provide the URL for my WSDL in SAP, the wizard througs the error "There are no services specified in the current WSDL file.".

I also tried the steps that are explained in the Wiki Tutorials, here the WSDL is not getting loaded and the "Get Data" button is always disabled.

I am using NetWeaver 7.0 for providing the Web Service.

Any help or pointers would be much appreciated. Thanks a lot in advance for all the help & support.

Best Regards

Kathirvel

What does the error event says in the error event handler?

"flightWS.addEventListener(FaultEvent.FAULT,onWSError);" The onWSError method's error parameter should have some useful information.

Hi Dan,

I was using the WSDL from SE80, hence it had some issues as the "Service" section was not found.

This thread was helpful.

Now, I generated the wsdl from SOAMANAGER and the system is able to load that. I got the WSDL loaded, but the I am not getting the results to the datagrid. Any help here is much appreciated.

Regards

Have you looked in the debugger to see what is being returned? Maybe the case is different?

Thanks Dan, I did check the event object, but I could find the table that will be returned from the ABAP WS.

But I tested in WS, the beloe are the results:

Request

- <SOAP-ENV:Body>
- <ns1:ZwsFlightGetlist xmlns:ns1="urn:sap-com:document:sap:soap:functions:mc-style">
  <Airline>AA</Airline> 
- <FlightList>
- <item>
  <Airlineid /> 
  <Airline /> 
  <Connectid /> 
  <Flightdate /> 
  <Airportfr /> 
  <Cityfrom /> 
  <Airportto /> 
  <Cityto /> 
  <Deptime /> 
  <Arrtime /> 
  <Arrdate /> 
  <Price>0</Price> 
  <Curr /> 
  <CurrIso /> 
  </item>
  </FlightList>
  </ns1:ZwsFlightGetlist>
  </SOAP-ENV:Body>

Response

  <CurrIso>USD</CurrIso> 
  </item>
  </FlightList>
  </n0:ZwsFlightGetlistResponse>
  </soap-env:Body>

My Code in mxml file


			private function getData():void{
				var operation:AbstractOperation = flightWS.getOperation("ZwsFlightGetlist");
				var input:Object = new Object();
				input.Airline = txtAirline.text.toUpperCase();
				input.FlightList = flightData;
				operation.arguments = input;
				operation.send();
			}

			private function onFlightWSGotResult(event:ResultEvent):void{
				flightData = event.result.FlightList;
			}

Note: The rest of the steps are same as the SDN wiki example.

Am i missing something here? Could you please help?

Regards

This looks like XML output, what do the objects look like onFlightWSGotResult? Does the event.result have anything in it?

Dan,

This is the content of the "event.result".

event.result = mx.collections.ArrayCollection (@2f84241)	
	dispatchResetEvent = true	
	filterFunction = null	
	length = 0	
	list = mx.collections.ArrayList (@3035b51)	
		[inherited] = 	
		length = 0	
		source = Array (@2fca7b1)	
			length = 0	
		uid = "820E6DA7-0199-C1B2-F3F0-63576D461244"	
	sort = null	
	source = Array (@2fca7b1)	
		length = 0

Hi Dan,

I am getting results in the event.result as given below, but this is not getting displayed in the DataGrid.

I add the below line in the getData() function, as FlightList is a table parameter in my RFC function module.

input.FlightList = "";

Could you please help?

Dan,

Thanks a lot for your help. I made the below two changes and it is working fine.

private function onFlightWSGotResult(event:ResultEvent):void{
	dbFlightData.dataProvider = event.result;
}

<mx:DataGrid x="10" y="36" width="608" height="331" id="dbFlightData">

Regards
