Creating a new Geoprocessing widget

PrestigeMakanga — Thu, 04 Nov 2010 11:32:37 GMT

I am running a geoprocessing service and would like to consume the service in the ArcGIS viewer for flex. i understand I have to create a widget for this. Would anyone be able to assist me in this regard. The link to the GP service is http://cuo.geomatics.uct.ac.za/ArcGIS/rest/services/CUO_Tools2/GPServer/Buildable_Accessible_Areas and I have attached a picture of the interface as is appears in a pp based on the ArcGIS server ADF.

Prestige,

I can not get anything other than job failed using this service even from your rest service directory link you provided... Any Ideas?

It works within REST if you use the following as an input at http://cuo.geomatics.uct.ac.za/ArcGIS/rest/services/CUO_Tools2/GPServer/Buildable_Accessible_Areas/submitJob and then wait almost a minute:
{ "distance" : 0.5, "units" : "esriMiles" }

Result:

I am running the service successfully in the following app. http://cuo.geomatics.uct.ac.za/informalsettlements/. It is also running fine through arcgis explorer.

Can some access constraints on our server possibly cause this?

Robert, on the above link click on the "potential housing land" task to see the default input values. If you just click submit it should. I am still refining the model so at the moment it returns a result after about 5 mins.

I have attached a typical result from running the model. I have run it with two different sets of parameters as shown by the different colours. If you still have a problem with running the GP service let me know.

Prestige,

Have you read these articles about deploying GP Processes for use in server? Most people think that just because it runs in ArcMap that it will work fine for the web and normally it does not. By the looks of it you have this figured out though as you are running it from your web adf site. My big question is are you publishing a MXD or a toolbox when you deployed this to the server?

I have not read these specific articles since I am still on 9.3.1. But I have understood the basics of publishing a model from the 9.3.1 tutorials.

I am publishing a tool box. So r u still getting errors in running the model?

What is the WKID you are using for the GP Task?

Hi Robert,

Surprisingly i got the same error today. However the service is now running ok after clearing the output Geodatabase. Try and see if it does not run fine now. Let me know if there are any other errors.

I am not inserting any wkid through the adf app or in explorer.

Prestige,

Here is a widget for your GP Task. I have test and it works well.

Hello Robert,

The swf file is not being generated when I compile the code in the flash builder. I am also getting an error on upon trying to view the design (see image attached). Would you please send me the compiled version.

Regards
Prestige

Prestige,

So if the swf was not being generated than you probably forgot to add the mxml to your projects modules list... Anyway here is the compiled and uncompiled versions and the flexviewer config file that I used for testing.

Thanks a span Robert,

The tool is working fine.

Kind regards

Hi Robert,

I have since changed to the ESRI Base layers. The model seems to run fine but the results are displayed on the original extent that you set in the configuration. So I thought it must have been a projection problem so I have converted the model result to the WGS 84 (though i thought this should have been done on the fly) to match the esri street map projection. But still the results are not overlaying see http://cuo.geomatics.uct.ac.za/flexviewer/.. However the results are displayed fine in Explorer.

Did you ever test the widget with the esri base layers? Any idea how i can correct this?

Regards
Prestige

Prestige,

You need to look at the spatial references that you are using. The esri base maps that you are now using are actually WKID 102100 (WebMercator) and not WGS 1984. And your data is using some unique WKT (Well Known Text) and not a WKID (Well Know Id). The WKT is OK with ArcGIS Server 10 but because of this I did not specify in the code for the widget the spatial reference that the GP would use

                                      //gp.outSpatialReference = map.spatialReference;
      //gp.processSpatialReference = processSR;

You will need to uncomment these line in the code and I am still not sure this will fix the issue. The way to make your mapservice the fastest is to to have your data match the WKID of the base map data which is WKID 102100
