ESRI Route Service for Locate Widget

MichaelVolz — Mon, 04 Mar 2013 14:27:58 GMT

To All FlexViewer Users and Developers:

By default from the Locate Widget download, I am using the follower routing service:

<routetasksolver>http://tasks.arcgisonline.com/ArcGIS/rest/services/NetworkAnalysis/ESRI_Route_NA/NAServer/Route</routetasksolver>

According to the following url:

http://www.arcgis.com/home/item.html?id=4078fece745140d7af17bf74b5f300fd

The above routing service is on extended support and I should use the newer World Route service instead

http://route.arcgis.com/arcgis/rest/services/World/Route/NAServer

but when I try to access this URL or just http://route.arcgis.com/arcgis/rest/services

I get Error: Services Directory has been disabled Code:403

Does anyone know the proper URL to access this newer routing service?

Any help or hints are greatly appreciated. Thank you.

Michael,

The http://route.arcgis.com/arcgis/rest/services/World/Route/NAServer url is fine, but you will not be able to see the rest service directory for this page by just typing it into a browser as the service directory has been disabled. It will still work in your widget though.

I incorrectly posted this as the Locate Widget when I should have referred to it as the Route Widget, which both of you understood. Sorry about that.

This is the first line in my modified RouteWidget.xml file.

<routetasksolver>http://route.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route</routetasksolver>

When I use this URL in the route widget, I get a sign in screen which I populate with my AGOL for Organizations account.

Unfortunately, I get the error 9004$LAYER_NOT_EXIST. Clear and start again or add another valid stop.

If I click the reset button and add 2 more points, I still get the same error message.

Robert:

Can you try using this URL in a test flexviewer app that has the route widget in it to see if you get the same results?

Any help or hints are greatly appreciated.

Michael,

When I get a chance I will test against this new service but in the mean time just use the one that comes default in the widget.

Re: ESRI Route Service for Locate Widget

MichaelVolz — Mon, 04 Mar 2013 16:14:39 GMT

Will do Robert.

I was just looking to get a route service that might have had more up-to-date data as I know of places where the road alignment has changed in the past couple of years and these are not included in the default route service data.

Robert:

Could it be that this is a secured service, as it requires AGOL for Organization credentials, and both the OOTB and your modified Route Widgets do not support the use of a secured service as the widgets are currently coded?

Re: ESRI Route Service for Locate Widget

RobertScheitlin__GISP — Mon, 11 Mar 2013 18:17:52 GMT

Michael,

That seems to be the case using the old URL did not require authentication and the new one does. As I do not have an AGOL account I am now unable to test/develop using the new url, so I guess this widget will become obsolete.

I'm not sure what you mean with the OOTB Route Widget?

This isn't released yet... but in version 3.2 we will add a new Directions (as in driving directions) Widget for this purpose.

Thanks Robert.

Does anyone know where I would change the uncompiled code on the Route Widget to allow the use of secured services?

Just FYI for people who don't have their own route service:
For testing a non-authenticated route service (only covers San Diego):
http://sampleserver6.arcgisonline.com/arcgis/rest/services/NetworkAnalysis/SanDiego/NAServer/Route

For authenticated service - requires an arcgis.com account that is part of an arcgis.com organization (a 30-day free trial is available at http://www.arcgis.com/about/trial.html):
http://route.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route

Bjorn:

I understand that I need to use the Route Service URL you are specifying.

http://route.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route

The problem is when I try to use the Route Widget with this newer secured service, after I enter my AGOL for Organizations account credentials, I get the following error:

Unfortunately, I get the error 9004$LAYER_NOT_EXIST. Clear and start again or add another valid stop.

How do I configure the widget (easier) or the uncompiled code (difficult) to accept the secured service?

Re: ESRI Route Service for Locate Widget

BjornSvensson — Mon, 11 Mar 2013 18:59:38 GMT

Michael, I am not familiar with the code for Robert's route widget (and I'm still confused what you mean with "OOTB route widget"), but as long as your application have enabled IdentityManager (which the flexviewer does by default) you should get prompted to log in.

I'm guessing this might be working for you, and it's at a later step you get the error.

What is the exact REST request and response that you are seeing?

IdentityManager is already enabled (and should prompt as needed):

Bjorn:

As per a previous thread I have the following setup and I am generating the following error:

This is the first line in my modified RouteWidget.xml file.

<routetasksolver>http://route.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route</routetasksolver>
(I've also tried <routetasksolver>https://route.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route</routetasksolver>)

When I use this URL in the route widget, I get a sign in screen which I populate with my AGOL for Organizations account.

Unfortunately after I enter my destination point, I get the error 9004$LAYER_NOT_EXIST. Clear and start again or add another valid stop.

If I click the reset button and add 2 more points, I still get the same error message.

I thought you have said that the IdentityManager should already be enabled so the Route service should work successfully.

RobertScheitlin__GISP — Tue, 12 Mar 2013 12:13:26 GMT

Michael,

He did not say that MY widget would work with this new service URL (it is not his job to know about 3rd party widgets, and esri does not have a OTB route widget in version 3.1 or below). When you use that new new service it presents you with the IdentityManager and you provide your AGOL credentials, so the IdentityManager is doing its stuff correctly. There must be a change in how the Route service works that my widget is not handling and as I am not an AGOL Subscriber I currently have no way of testing. You are going to have to use the default url provided with my widget untill 3.2 comes out and then you will need to switch to the esri OTB directions widget.

Re: ESRI Route Service for Locate Widget

BjornSvensson — Tue, 12 Mar 2013 12:18:01 GMT

Which version of flex viewer are you using? 3.1?
Are you compiling the source code with flex viewer, or using application builder, or the compiled zip version?

Re: ESRI Route Service for Locate Widget

MichaelVolz — Tue, 12 Mar 2013 12:27:11 GMT

Thanks Robert.

I will wait until Flex 3.2 comes out and test if it works then.

Re: ESRI Route Service for Locate Widget

RobertScheitlin__GISP — Mon, 18 Mar 2013 17:07:01 GMT

Michael,

The version 3.1.1 of my route widget now supports the new AGOL route service url.

Re: ESRI Route Service for Locate Widget

MichaelVolz — Tue, 19 Mar 2013 14:29:35 GMT

Thanks for the update Robert.

I have replaced Route Widget Build 3.1 with your new Build 3.1.1 version. Unfortunately, now I can the progress clock to appear when the Flex App is loading and it is not going away. Any idea why this would be occurring?

I cleared the local browser cache and I analyzed traffic with Fiddler, but nothing jumps out as a problem.
