Call a GP Service in FlexViewer 2.3.1

francescodi_vito · ‎07-05-2011

Hy guys
i develop a model ain ArcGis 10 and i publish it as a Map Service with a Tool Layer. The GP Service is Synchronus and he works very well. i need to change the GP Service in Asynchronous but i tried to change my script but don't works.
i post here my script for my model synchronus

can anybody tell me how to modify my script for set my GP Service as Asynchronous?
help please
Thanks

YungKaiChin · ‎07-05-2011

1. Make sure the service support asynchronous geoprocessing ... (it will show in the fault msg)
2. Change execute to submitJob geoprocessTask.submitJob(parms);
3. Change event executeComplete > jobComplete

The reference can be found here:
http://help.arcgis.com/en/webapi/flex/apiref/index.html?com/esri/ags/tasks/JobInfo.html&com/esri/ags...

http://193.204.163.134/ArcGIS/sdk/rest/index.html?gpserver.html - ArcGIS Server REST API

gpService.execute(params, new AsyncResponder(gpServiceResultHandler, gpServiceFaultHandler));

...

private function gpServiceResultHandler(data:Object, token:Object = null):void
{ //do smthing with results }

private function gpServiceFaultHandler(fault:Fault, token:Object = null):
{ //do smthing with faults }

Also in last Flex Viewer from ESRI you can find DataExtractWidget - it works with GPServices.

looking on your service, i cant find "SubmitJob" in supported operations

execute()
submitJob()

francescodi_vito · ‎07-06-2011

hi
in my service you don't see submitJob because i set it Synchronous. When i tried with submitJob i change the service property.
I try with your help and after i will wrote for the responce
Thanks

francescodi_vito · ‎07-06-2011

can you give me a link for download the DataExtractWidget?
thanks

IvanBespalov · ‎07-06-2011

Just download Flex Viewer 2.3.1 source code - in widgets package find DataExtractWidget.mxml

francescodi_vito · ‎07-06-2011

Hi Ivan, thanks.
Now i try the code that you give me and after i say you if it works good
thanks

IvanBespalov · ‎07-06-2011

Hmmm. Now I understood the meaning of your question.
:confused:

"ykchin" advised you how to solve you problem. No more - only 3 steps.

I just tried to show you where you can get help.

francescodi_vito · ‎07-06-2011

hi Ivan
I followed the instructions of "ykchin" but the model don't get me a result.

private function startGeoProcess(event:MouseEvent):void
   {
    
    
    var parms:Object = new Object();
    parms.Condizione = String(condizione.text);
    parms.Valore = Number(valore.text);
    
    
    var geoprocessTask:Geoprocessor = new Geoprocessor();
    geoprocessTask.outSpatialReference = map.spatialReference;
    geoprocessTask.showBusyCursor = true;
    geoprocessTask.url = "http://193.204.163.134/ArcGIS/rest/services/ENEA/Cap_Term_Vol_MAX/GPServer/CapTermVolMAX";
    geoprocessTask.useAMF = false;
    geoprocessTask.submitJob(parms);
    geoprocessTask.addEventListener(GeoprocessorEvent.JOB_COMPLETE, executeCompleteHandler);
    geoprocessTask.addEventListener(FaultEvent.FAULT, faultHandler);
   }
   
   private function executeCompleteHandler(event:GeoprocessorEvent):void
   {
    
    
    var myPointSymbol:SimpleMarkerSymbol = new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_CIRCLE, 10, 0x1AA1D3, 0.2);
    
    
    for each (var graphic:Graphic in event.executeResult.results[0].value.features)
    {
     graphic.symbol = myPointSymbol;
     graphicsLayer.add(graphic);
     map.addLayer(graphicsLayer);
     
    }
   }
   
   private function faultHandler(event:FaultEvent):void
   {
    if (event.type == "fault"
     && event.fault.name == 'Error'
     && event.fault.faultCode == '500'
     && event.fault.faultString == 'Error Executing Task')
    {
     Alert.show("Oops - no results.  Try clicking in an ocean...");
    }
    else
    {
     Alert.show("Unexpected fault:\n" + event.toString());
    }
   }

In your opinion is there a error?
With Synchronous model and the original code that i post, i have a result. But the model takes a long time to run and after 2 mitutes in my application i have a worning by plug-in of ShockWave Flash, because because it's been a long time.
What do you think?
Help

IvanBespalov · ‎07-06-2011

Sorry, but my English is so poor... i can't describe you how to... I tried to give you links to ESRI help.

Just feel the difference between

screen3.png (ESRI sample service) - support asynchronous geoprocessing
and
screen2.png (your service) - NOT support asynchronous geoprocessing
