Closest Facility Error 400- Invalid URL

RamiSourani — Tue, 07 Dec 2010 12:23:29 GMT

Greetings,

I am working on Closest Facility in Route Task (myRouteTask.SolveClosestFacilityAsync)
I am using the same code in http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ClosestFacility
but using my service published in our server.

The SolveClosestFacility_Failed is triggered and having the error message = "" (Just "Network Analysis error" in the message box)

I have checked ESRI Closest Facility REST layer http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Network/USA/NAServer/Closest%20Facility with respect to mine,
The difference was that I don't have "Supported Operations: Solve Closest Facility" in my REST Closest Facility layer

Am I missing some settings to enable "Supported Operations: Solve Closest Facility"?

FYI: Below link is on my intranet just putting it for your reference:

Thank you

Have you tried making the web request from your web browser directly? This URL exists? http://sourani-pc/ArcGIS/rest/services/LAND/NetworkDS/NAServer/Closest%20Facility/solveClosestFacility
Try to put the input parameters here as you see them from Fiddler when your app makes the request.

Kindly look at Post#14 from this thread for reference http://forums.arcgis.com/threads/14730-Area-And-Perimeter

I already did this:

Just a note, my problem is in the Nearest Facility layer, it does not have "Supported Operations: Solve Closest Facility" as seen in ESRI Facility Layer when viewed in the browser.

The question is why I don't have it and how can I add it, is there some settings should be made? or anything else?

Thank you

Re: Closest Facility Error 400- Invalid URL

JenniferNery — Tue, 07 Dec 2010 16:30:21 GMT

What I mean to say is go to the Network Analyst service directly such as
http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Network/USA/NAServer/Closest%20Facility/solveClosestFacility
and enter each input separate as displayed on Fiddler's Inspectors WebForms (see the screenshot from previous link).

See if you still get the same results as when you did when you copied the web request URL.

Maybe the Network Analyst service itself is inaccessible or the web request is not correctly formed. It's easier to identify the problem when you do one step at a time.

Dear Jennifer,

I don't have the "Solve Nearest Facility", this is my problem,

For example in Route layer, if I click on Solve, I can enter the parameters, but in the Nearest Facility I don't have anything to click on.

Kindly check attached screenshot,

Thank you for the support.

Re: Closest Facility Error 400- Invalid URL

JenniferNery — Tue, 07 Dec 2010 17:00:14 GMT

Oh okay, then that caused the Invalid URL. The problem then is how the Network Analysis service is setup and published, not the query formed by the web API.

Please try to visit the following help doc: http://help.arcgis.com/en/arcgisserver/10.0/help/arcgis_server_dotnet_help/index.html#//009300000055000000.htm

If you have further question about this, you might get answers from the ArcGIS Server forum.
