Geoprocessing problem

PaulHuppé — Mon, 01 Nov 2010 11:35:42 GMT

Hi,

I have setup a test Python script which simply accepts 2 parameters and which returns an email to the user. I have included the script in a Toolbox and have published the Toolbox. If I run the Python script manually, it works. If I run the tool using the REST interface, it works. When I try to run it from inside my Silverlight application, it just hangs. It does not even seem to make it to the server. Following are some pieces of the code I am using. Can anyone spot the problem?

Thanks,
Paul

            string restServerURL = "http://myserver.name/ArcGIS/rest/services/";
            Geoprocessor geoprocessorTask = null;
            // Start timer for task
            _processingTimer = new System.Windows.Threading.DispatcherTimer();
            _processingTimer.Interval = new TimeSpan(0, 0, 0, 5, 0);
            _processingTimer.Tick += ProcessingTimer_Tick;
            _processingTimer.Start();
            geoprocessorTask = new Geoprocessor(restServerURL + "TestSendEmail/GPServer/SendEmail");
            geoprocessorTask.UpdateDelay = 5000;
            geoprocessorTask.JobCompleted += GeoprocessorTask_JobCompleted;
            List<GPParameter> parameters = new List<GPParameter>();
            // Pass the user's email to send them the zip file
            parameters.Add(new GPString("EmailTo", tbEmail.Text));
            // Pass the layer names to the Geoprocessing service
            parameters.Add(new GPString("DesiredLayers", _layerNames));
            geoprocessorTask.SubmitJobAsync(parameters);

Have you tried running Fiddler while you run your SL app to see where it hangs? Also, have you tried debugging the SL app to see if the parameters it passes to your task are correct? Can you also try to use the same parameters in the browser? You can look at this post for reference post# 14 http://forums.arcgis.com/threads/14730-Area-And-Perimeter

Hi Jennifer,

I have tried debugging the SL app and the parameters are ok. I got the information from Fiddler and tried it in the browser

I got the following result:

{"error":{"code":500,"message":"Error Submitting Job","details":[]}}

But, if I do the same thing via the REST intnterface,

I get:

You used the same parameters found in Fiddler under Inspectors > WebForms tab? The error 500 that you see is a ServiceException from JSON. Unfortunately there are no further details, usually details will say invalid input. But you said the parameters from SL app when used in the browser will submit the job without error. I'm not sure what to tell you. I'll check whether URL encode has something to do with it.

Yes, I used the same parameters. It sucks that we do not get any information from the error message. It does not help much!! I wish I knew what to try next!

Is this the correct input name?

Hi Jennifer,

Yes, that was it!!! I have been starring at this stuff for so long, I could not spot the obvious.

Thanks,

Hi Guys,

I know this thread is old, but I am so happy that you helped me find my problem, I wanted to say thanks.

You know, I spent SO much time checking, and re-checking the input parameter values and testing using the services directory, I never actually double checked the input parameter names themselves. Duh!

Such relief!

Cheers,
Richard.

Hi,

Glad this could help. Sometimes the obvious errors are the hardest to spot!!!

Hello folks, i am having the same issue, and i was wondering what the restrictions are for naming conventions in geoprocessing task parameters (async). I have a service with 3 parameters, all are of GPFeatureRecordSetLayer dataType. I know the names are strange, but thats just the way our in house dev team set them up so i can test them. They are as follows(everything within the "" is a part of the parameter name):

"Enter a Graphical Boundary or a Boundary Feature Class:"
"Traffic_Zone_2001_POP2001"
"Blank.DBO.Blank_Boundary_Land"

the url i am using in the geoprocessing task is as follows:

http://geoserver1/ArcGIS/rest/services/YrGeoView_Population_tools/Model3/GPServer/Model 3a Traffic Zone Population Estimate

These names will change before they are delivered, but i wanted to check with the community to be sure. The 2032 stream error is so annoying. Thanks everyone

Hi,

If this is the URL you are trying to use, then I believe it needs to be encoded.

the url i am using in the geoprocessing task is as follows:

http://geoserver1/ArcGIS/rest/services/YrGeoView_Population_tools/Model3/GPServer/Model 3a Traffic Zone Population Estimate

You should try

http://geoserver1/ArcGIS/rest/services/YrGeoView_Population_tools/Model3/GPServer/Model%203a%20Traffic%20Zone%20Population%20Estimate

Thank you for your response paul. I have updated the gp service with the new URL, and changed my parameter names to have underscores. my geo processing code looks like this:

    var params:Object = new Object();
    params = { 
     "Enter_a_Graphical_Boundary_or_a_Boundary_Feature_Class_": boundryFS,
     "Traffic_Zone_2001_POP2001": popFS,
     "York_DBO_York_Boundary_Land": landFS}; 
    gp.useAMF= false;
    gp.submitJob(params);

and my gp task looks like this in code:

 <esri:Geoprocessor id="gp" url="http://geoserver1/ArcGIS/rest/services/YrGeoView_Population_tools/Model3/GPServer/Model%203a%20Traffic%20Zone%20Population%20Estimate"
        fault="gp_faultHandler(event)" useAMF="false"
        jobComplete="gp_jobCompleteHandler(event)"
        executeComplete="modelServices_executeCompleteHandler(event)"/>

I will update this post with images of my service end point. I appreciate any feedback on this matter. Thanks

EDIT: I have attached some shots of my rest end point and parameters, in case they show any obvious issues:

AND

Sharing these images with imageShack, but they dont seam to show up in the IMG tag's.
I am still getting the stream error 2032. Thanks for looking at my issue.

Is it now working for you with these changes? If so, I am glad I could help.

I am afraid it is still causing me grief, but i am grateful for your assistance.

Re: Geoprocessing problem

You can try using Fiddler to see all the communication between the application and theservice. Sometimes that helps.

Thanks for the tip paul, i havent tried fiddler, but it looks to be responding with the same kind of data firebug was. The response is as follows:

# Result Protocol Host URL Body Caching Content-Type Process Comments Custom
57 500 HTTP geoserver1 /ArcGIS/rest/services/YrGeoView_Population_tools/Model3/GPServer/Model%203a%20Traffic%20Zone%20Population%20Estimate/submitJob 3,037 private text/html; charset=utf-8 firefox:6964

firebug shows the same thing. Do you have any suggestions on how to use fiddler effectively to help solve this issue? could this be a security issue on the server? The service is meant to create an output table (two actually, a file geodatabase and an access database). I can see the service is running in arcCatalog but i cant see any service output dir, or that the service has even run.

PaulHuppé — Mon, 22 Aug 2011 12:33:25 GMT

Fiddler will probably not show much more than Firebug. Like you, it seems you are also new to all this geoprocessing stuff. Does your model work fine if you try it directly in ArcGIS?

Re: Geoprocessing problem

morgandawe — Mon, 22 Aug 2011 12:39:28 GMT

The service does work when run from the dev machine through arcMap.
