Problems with Data Extraction GP Task

DonCaviness — Wed, 08 Sep 2010 19:05:21 GMT

I have created a data extraction gp task and I have run into a problem that I can't seem to figure out. In the gp service I have a list of choices that can be clipped, not all of the data is in the same coordinate system. I have my JS code set so that I can pass the proper params to the service. I am passing the "Layers_to_Clip", "Area_of_Interest", and "format" to the service, the service processes the information and I can get the zip file that is output. The problem is that the created shapefile does not have any data associated with it. At first I thought my service was the problem but I was able to extract any of the data using the Flex API. Here is my JS code that I am using. Does anyone know that the my issue could be?

var gpFeatureSet = new esri.tasks.FeatureSet();
var features= [];
    var xmax, ymax, xmin, ymin;
var mapExtentPoly;
var clipLayers = [];

        esri.config.defaults.io.proxyUrl = "proxy.ashx";
        esri.config.defaults.io.alwaysUseProxy = false;

var gp = new esri.tasks.Geoprocessor("http://server/ArcGIS/rest/services/DetailDataDownload_GP/GPServer/Extract%20Data%20Task");

    xmax = mapAll.extent.xmax;
    xmin = mapAll.extent.xmin;
    ymax = mapAll.extent.ymax;
    ymin = mapAll.extent.ymin;

    mapExtentPoly = new esri.geometry.Polygon(mapAll.spatialReference);
    mapExtentPoly.addRing([[xmin, ymax], [xmax, ymax], [xmax, ymin], [xmin, ymin], [xmin, ymax]]);

    var mapSymbol = new esri.symbol.SimpleFillSymbol();
    var mapGraphic = new esri.Graphic(mapExtentPoly, mapSymbol, "", "");
    mapAll.graphics.add(mapGraphic);

          features.push(mapGraphic);
    gpFeatureSet.features = features;

     layersToClip = clipLayers;

var params = {
    "Area_of_Interest":gpFeatureSet,
    "Feature_Format":format,
    "Layers_to_Clip":layersToClip
    };

        gp.submitJob(params, completeCallback, statusCallback);

Does anyone have an idea why I am having this issue?

My service works perfectly in ArcMap, it just fails when I use it via the web.

Did you ever solve this problem? I'm trying to do the same as you but I keep getting the error:
""esri.config.defaults.io.proxyUrl is not set"
Do you have any pointers?

I was able to solve my problem. The problem that i was having was related to a bug in the JavaScript API. I never did have an issue with using the proxyURL. For that all I did was download the proxy.ashx and proxy.config file from the Esri documentation and referenced it as the documentation stated.

OK, thanks for your quick reply. I shall endeavour to get to the bottom of this. Thank you.

Ben,

I had the same error ass you the other day... I had our SA set up an internet proxy on the server we are running our web app. A lot of the sample code from the .js API ESRI pages have a generic URL that points to a non-existent proxy.

If you don't have the sample code, just put this your init function:

esri.config.defaults.io.proxyUrl = "http://..../proxy.ashx" Make sure your server has permissions to read this too.
