Stuck on getting getResultImageLayer

SmaranHarihar — Wed, 24 Oct 2012 18:22:34 GMT

I am getting back the success from the GP Tool but for some reason, when I execute the,

gp.getResultImageLayer(jobInfo.jobId,"final_shp", imageParams, function(gpLayer) {    map.addLayer(gpLayer);     });

I am receiving an error on the map.addLayer(gpLayer). The error is,

Network Error: 500 Internal Server Error - <complete path of the job directory where the final.shp is created>. What is causing the layer not to be added to the Map? This is the link.

This is my code,

I see that output isn't in arcgisjobs but in your temp so it isn't accessible. Have you set variable stratchworkspace ? Name of Parameter output is final_shp (I see in code final.shp) and set it esriGPParameterTypeRequired.

Hi,

I apologize for the late response. Thank you for your reply. When I remotely log into the server and check for the jobs folder I am able to see the shapefile (final_shp) and it also has the results which I wish to display. The server wipes out all the job folders that were created at the end of the day. Here is the new job folder link and I am also able to see all the details of the output shapefile in this link as well.
I changed the final.shp to final_shp. My FLEX application uses the same GP Tool with the same settings and displays the output but I am not able to replicate it on Javascript.

Also this is the error that appears in the console,

"NetworkError: 500 Internal Server Error - http://webgis.arizona.edu/ArcGIS/rest/services/webGIS/Shock_Models/GPServer/Income_Log/jobs/jc47c82f39711494883b7e119f9b02b5d/results/final_shp?dpi=96&transparent=true&format=png8&imageSR=102100&f=image&bbox=%7B%22xmin%22%3A-14519891.438356264%2C%22ymin%22%3A637618.0139790997%2C%22xmax%22%3A-6692739.741956295%2C%22ymax%22%3A6507981.786279075%2C%22spatialReference%22%3A%7B%22wkid%22%3A102100%7D%7D&bboxSR=102100&size=800%2C600"

I see error:
Server Error - Object reference not set to an instance of an object when it's request image from mxd.

Have you set in gp service the Result Map Service of MapServer ?

Can you open request with support esri? it's difficult if I don't see model (settings, variable scratch ect.)

Hey ciava,

Thank you so much for your help. Actually there was some problem with the Geoprocessing Tool and I was finally able to resolve it.

Here is my application. You can place one or more points and it works great. It will take around 20-25 sec.

Just one more question.

If I want to create popups for gplayer how can I do that?

Re: Stuck on getting getResultImageLayer

Thanks again for the reply ciava. I actually wanted to display the information that the 'gplayer' has, which I am receiving from the getResultImageLayer.

gp.getResultImageLayer(jobInfo.jobId,"final_shp", imageParams, function(gpLayer) {
   map.addLayer(gpLayer);
    });

So now that I have added the layer onto the map, I wish to fetch the content details of the gpLayer. There are four main fields that gpLayer has and I want to add it to the popup info.

Like in the example you gave, which displays the Lat and Long, I wish to use the same popup feature but instead of Lat and Long in contents, I want to display the data in the gpLayer.

I hope I was able to explain well.

Hi ciava,

It seems now I am stuck on another problem. I have the results layer back on to the Map but it seems that none of the data is coming back. The url of the gpLayer that is coming back shows none of the fields that I need the output layer to have.

This is what the url output of the gpLayer looks like. As you can see there is no info about the layers that the layer is suppose to have, which can be seen in the final_shp layer that can be seen in the jobs folder.

Is this normal? How can I retrieve the info of the layer?

Re: Stuck on getting getResultImageLayer

nicogis — Mon, 19 Nov 2012 05:33:28 GMT

If I understand your question: yes, using result map service you return a image. It's rendered using map service and data in job folder but I don't see request rest passing from map server for get info on data.
(...If the GP service is associated with a result map service, the default output for GPRasterDataLayer and GPFeatureSetLayer parameters is a map image ...)

you have two solution:
you don't use result map service and you use only gp and render on client the output of gp
or
you use result map service but you must create a soe (server object extension) where you pass id of job and so you get on server your data (feature class, raster ect) and return on client the info that you need.
I have done a similar solution for a result map service yet set and so I don't want modify resutl map service (render complex) so I create a soe that from jobID (sent from client) I get feature class from server and serialize in json for js api esri.

Yes I also need the data which is there in the jobs folder on the server. How can I create this SOE to obtain the feature class from server? Can you pls share an example?

How can I render the output of gp on the client side? That is what I was trying initially remember, but I was getting the 500 Internal Server Error. Using the same gp tool when I used it with Map Service it worked fine.

So How can I render the output of the gp without the Map Service?

Re: Stuck on getting getResultImageLayer

SmaranHarihar — Sun, 12 Dec 2021 04:13:39 GMT

I tried using,

gp.getResultData(jobInfo.jobId,"final_shp", imageParams, addResults);
function addResults(results) {
  console.log(results);
  var features = results.value.features;
 }

But it keeps giving me the error,

TypeError: results.value is undefined

Is this the method to get feature info request from the data?

Re: Stuck on getting getResultImageLayer

nicogis — Sun, 12 Dec 2021 04:13:42 GMT

Ok, getResultData but you have a imageParams (old paste/cut) from remove ...

fix your code so


gp.getResultData(jobInfo.jobId,"final_shp", addResults, errResults);

function addResults(results) {
   console.log(results);
   var features = results.value.features;
   // do render ...
}

Sorry about that. I corrected the code to,

gp.getResultData(jobInfo.jobId,"final_shp", addResults, errResults);

function addResults(results) {
  console.log(results);
  var features = results.value.features;
 }
 
 function errResults(err) {
  console.log(err);
 }

The problem is that results.value.features returns empty array. The feature count is zero.

Still not getting back the results. This is my application.

Re: Stuck on getting getResultImageLayer

nicogis — Fri, 23 Nov 2012 17:52:29 GMT

The problem is that you use a gp with set A map so result is a image and not a recordset so you need change your gp in tab parameters and in "The tools exposed by Geoprocessing Service are stored in":
select radio button A toolbox and select toolbox.

But in your blog you have given this image, which helps get back the Map which is overlaid on the baselayer in my application.

I changed the parameter to A toolbox and now I am niether receiving the output Map Layer nor am I getting any results. The results.value.features still returns an empty array.

This is my application.

Re: Stuck on getting getResultImageLayer

nicogis — Mon, 26 Nov 2012 13:37:00 GMT

I have in response featureset with a exceededTransferLimit property. This property is true so the number of records exceeds the maximum number configured on you server. (I Have final.shp exceeded transfer limit of 1000 ).

If you have switch on toolbox you comment "gp.getResultImageLayer(j ..." and use only "gp.getResultData(.."
