Map Service won't show up in FlexViewer

PaulFrey — Thu, 27 May 2010 11:42:22 GMT

So i have a published map service that is running fine, if I go to its actual URL in a browser it is there and it is running. However when i link it into the FlexViewer it will not show up. I have it programmed in as a Live Map and a basemap and neither of them show. I'm really hoping someone else has had this problem and its an easy fix. Does anyone have any clues as to what is going on? Any help would be greatly appreciated.

Paul,
I'm Having the same problem. I can get the sample online map service to show no problem, but when I add my own service the map doesn't show. I believe it has something to do with the extents.

Here is a snippet of my code so far...

<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="http://www.adobe.com/2006/mxml"
xmlns:esri="http://www.esri.com/2008/ags"
pageTitle="Example - ArcGIS API for Flex connecting to a dynamic AGS service">
<esri:Map>
<esri:ArcGISDynamicMapServiceLayer
    url="http://gis-server2/ArcGIS/services/GPS_2010/MapServer"/>
</esri:Map>
</mx:Application>

Not much, but I'm at day one with this!

Dave

I just talked to tech support and the problem was my url was pointing to the wrong place.

Try http://YourServer/ArcGIS/rest/services/YourService/MapServer

Also, It was necessary to run Web Applications Post Install again for some reason

Start>ArcGIS>ArcGIS Server for the Microsoft .NET Framework> Web Applications Post Install

Hope this helps

Paul,

You may also need a crossdoamin.xml file if your ArcGIS server and your web application are not on the same machine.

PaulFrey — Fri, 28 May 2010 16:49:25 GMT

ok i put crossdomain.xml and policyfile.xsd in the same folder online as my config.xml. Its still not showing up, the option to turn on the livemap isnt isnt even there anymore...do i need to put crossdomain somewhere else? This is also what my cal to the map service looks like, from th config.xml file:

<mapservice label="Parcels" type="dynamic" visible="true" alpha="0.75">http://rptsweb.cattco.org/ArcGIS/rest/services/FlexTest1/MapServer</mapservice>

if that helps in anyway. I appreciate the tips guys, hopefully I can figure this out soon.

Paul

The crossdomain.xml file should go at: http://rptsweb.cattco.org/crossdomain.xml

ArcGIS Server 10.0
Flex Viewer 2.1
Machine #1: SOC & SOM
Machine #2: Dedicated Web server machine
Machine #3: my PC Flex 4.0 (not deployed)
None of my map services will show up; http://gcgis/ArcGIS/rest/services/Static/StartUp/MapServer
Sometimes the ESRI map services will show up.

I am having the same problem as the title of this post. I cant get any of the published maps from my server to load as a basemap.

Everything is on the same machine (ARCSOM/ARCSOC/ArcServer 9.3.1, SDE, Maps, Data, etc) so I do not believe a crossdomain xml file is necessary.

I am only trying to add one basemap and no operational layers; projection shouldnt be an issue.

I can add basemaps from ESRI and other ones (like pfrey17's)

When I try to add one of my services, I get a blank map (see attachment)

All services are listed in the services manager and are functioning.

Any suggestions?

Can you post your map config?

Re: Map Service won't show up in FlexViewer

dpaddock,

The only thing I did to the out of the box version was;

1. Comment out the default basemaps.
2. Add my code (I've obfusicated the sensitive parts with <> )
3. Delete all the operational layer entries (in the version on my server, they are commented out)

I'm thinking its a security or arcserver setting on the server, no? If you still need me to post the XML, I will.

Thanks

Daniel,

No it is probably as simple as you did not update the initial extent property to match your datas spatial reference. No attachment by the way.

Re: Map Service won't show up in FlexViewer

DanielOchoa — Tue, 11 Jan 2011 14:42:36 GMT

I forgot to mention that I did update that intitial extent. I got the intitial extent by looking at the service in the REST service manager list.

I'm attaching the file to this post. Again, certain elements have been changed for security. All I'm trying to do is get one basemap to work. Nothing else. Can't even get that far...

Can you use a tool like HttpFox to look for requests to your service and see what the responses are? Is your Viewer on the same web server as your ArcGIS Server?

Re: Map Service won't show up in FlexViewer

DanielOchoa — Tue, 11 Jan 2011 15:57:27 GMT

I will try using HttpFox. In the meantime, I ran through this checklist:

1. I was able to use the Services Directory to make sure I had the right name, e.g.
http://localhost/ArcGIS/rest/services/

2. I opened the URL in a browser, and was able to read the metadata:
http://localhost/ArcGIS/rest/services/<folder>/MapServer

3. I can view the map with the JavaScript API link on that page:
http://localhost/ArcGIS/rest/services/<folder>/<map>/MapServer?f=jsapi

Everything is on one server. I'm even working on the viewer on the server.

Thanks,

Here is a screencap from my httpfox attempt. Looks like it is looking for a crossdomain file. I didnt know you had to have one; I thought you only needed one if you were doing cross-server data exchanging. I guess I'll try making one and throwing one in.

Re: Map Service won't show up in FlexViewer

DanielOchoa — Tue, 11 Jan 2011 16:51:03 GMT

ANSWER:

Ok, that did it. I added a crosssdomain.xml file to the c:\inetpub\wwwroot folder with this in it:

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*"/>
</cross-domain-policy>

And all of a sudden it worked. Again, since everything is on one server, I dont know why I would need it, but it works.

Thanks to everyone for the assistance!

You need a crossdomain.xml file if the domains in the urls are not identical.

Even if the Viewer url was http://127.0.0.1/... and the service url was http://localhost/... it would try to load a crossdomain.xml file.

Re: Map Service won't show up in FlexViewer

DanielOchoa — Tue, 11 Jan 2011 23:04:34 GMT

dpaddock,

Ok, I get that part. But I see now that this only works on the server that its being built on. Across the network, same thing as before - no map. So, I'm thinking something else has to be added to the crossdomain.xml, but I thought these two lines;

<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*"/>

...would pick up and allow requests from anywehere, no?

If not, can you tell me how this should look to allow access from anywhere?

Thanks!

Daniel,

Localhost or a loopback IP address is going to mean something else on a different machine so you need to be using the machine name instead and you need to verify the the machine name is being resolved on the network. So try something simple and enter the following url on a machine in the network that is not the host machine http://machineName/ArcGIS/rest/services and see if it resolves and displays the REST Service directory page.

Re: Map Service won't show up in FlexViewer

DanielOchoa — Tue, 11 Jan 2011 23:55:47 GMT

rscheitlin,

Tried that - its resolves not only to the machine name, but the alias and the IP as well. I can use any of those in front of "ArcGIS/rest/services" (i.e. http://<any of the above works>/ArcGIS/rest/services )

Here is my crossdomain file:

<?xml version="1.0" ?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" />
<site-control permitted-cross-domain-policies="all" />
<allow-http-request-headers-from domain="*" headers="*" />
</cross-domain-policy>

Thanks for the continued support....
