NA Route Rest services gives error

MuhammadWaqar_ul_islam

I have create Na Routing sample to test
on arcgis info its works fine create route on the data
but when i create Network Analysis services through Arcgis server and using rest services in silverlight sample
http://help.arcgis.com/en/webapi/silverlight/3.0/samples/start.htm#Routing
its gives error
Black"Routing error: Unable to complete operation unable to find atribute invalid Context" my rest services

Muhammad,

From your previous message it looks like you have already gotten a valid route back from the server.

The only step is left is to make your Silverlight application send the same HTTP parameters to the server endpoint: use RouteTask, RouteParameters, and RouteResult classes from the ESRI.ArcGIS.Client.Tasks namespace.
Here is a good sample how to use route endpoint in Silverlight: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#Routing

MuhammadWaqar_ul_islam

Hi Muhammad,

Please open the Route description page (http://<server>/ArcGISSERVER/rest/services/Network_ANAlysis/NAServer/Route) in a browser and look for all the attributes of the esriNAUTCost usage type; write down the name of the attribute you are interested to solve on.

Next, in your HTTP request, specify the impedanceAttributeName parameter with the value set to attribute name you noted at the previous step.

Please let us know what will be the result.

Hi Muhammad,

Please open the Route description page (http://<server>/ArcGISSERVER/rest/services/Network_ANAlysis/NAServer/Route) in a browser and look for all the attributes of the esriNAUTCost usage type; write down the name of the attribute you are interested to solve on.

Next, in your HTTP request, specify the impedanceAttributeName parameter with the value set to attribute name you noted at the previous step.

Please let us know what will be the result.

help me out please

i have open the _ags token layer ( from output directory of arcgisserver) in arcmap
and solved the solution in arcmap
its works fine
no error occurs
what next to solved this issue

DmitryKudinov

Hi Muhammad,

Looking at the error message, it might be the case that the network dataset on your Server is different from the one you used in ArcMap during service authoring (when you were creating the MXD which was later published).

So, please first verify that the network dataset on server is the same.

If network dataset is exactly the same on both Desktop and Server and service still fails, rerun the same request again and note the error message, particularly the part about "NALayer saved on server with token ...". The token value will tell you the name of LYR file in ArcGIS Server output directory (_ags<token>.lyr) - find this file, open it in ArcMap, and try solving it. Most probably the solve will fail in ArcMap as well and this will give you much better clue on what is going wrong.

what next to solved this issue

DmitryKudinov

Hi Muhammad,

Please try building a route on your network dataset using ArcMap first - will it work?

If it works, then download Fiddler http debugger tool (http://www.fiddler2.com/fiddler2/version.asp) and have it running while sending requests from your Silverlight application.

Check with Fiddler that all the attributes which are sent by the application present in your network dataset.

if there are some invalid attributes in requests whereas you do not specify them in your Silverlight code, try overriding these values explicitly.

Let us know if it doesn't help.

Dmitry
