Loading Map Service is blank

AndyWhitley

When I add my own map service to my flex project, the map is always blank. I can preview my map using the java script link within rest services and preview the map in arccatalog. Any suggestions? I am using arcgisonline for my other default base maps.

Patrick setting the view to true shows the points! Thanks everyone for the help. When I set it to false and then clicked the button that was created within the viewer (top right) it would never show up when I toggled it on?

Robert, yes I do use it in the code with the same url, it opens with a blank map and my points do not show.

main config initial extent looks like this:

initialextent="-8781000 4013000 -8636000 4069900"

Andy,

If you visit the following link do you see the cross-domain file?

http://intrfce/crossdomain.xml

Also, just to make sure we are on the same page. In the Web application are you turning the service on. Your code is set to visible=false which would force you to turn the layer on in the Web application before it would be visible. Try the following.

<layer label="AVL" type="dynamic" visible="true"
url="http://intrfce/arcgis/rest/services/Unit_AVL/MapServer"/>

Andy,

No, I mean when you use that url as the url for the layer in your config.xml

<layer label="AVL"    type="dynamic" visible="false"
                   url="http://intrfce/arcgis/rest/services/Unit_AVL/MapServer"/>

AndyWhitley

It displays the spatial reference is 3857, the link opens up the same as the last one, just my services directory page.

rscheitlin

Andy,

So in the Service directory page what does it say the WKID (spatial reference) is? What does your main config inital extent look like?

Does it work if you use this url then?

http://intrfce/arcgis/rest/services/Unit_AVL/MapServer

AndyWhitley

Robert,

Thanks for all your help today. Yes it does open up the services directory.

Andy

rscheitlin

Andy,

When you paste:

http://intrfce/arcgis/rest/services/Unit_AVL/MapServer

in a browser window does it bring up the Rest service directory page for that map service?

AndyWhitley

I added /rest/ before services also, left that portion out by mistake, still no luck.

Patrick,

The projection was already correct for the .mxd. I have included the code below for the map service. I have tried it with the internal ip address in place of the name of the server which is "intrfce" and tried it with www. in front of the server name also.

<layer label="AVL" type="dynamic" visible="false"
url="http://intrfce.com/arcgis/services/Unit_AVL/MapServer"/>

AndyWhitley

The flash build is on a different computer so I did add the cross domain file to the server and still no luck. Let me double check the projection and retry.

PatrickWard1

Do you have ArcGIS Server installed on a different server than the one hosting your Flex application? If so the remote server needs to have a cross-domain file in the root directory. For security reasons, the Web browser cannot access data that resides outside the exact Web domain where the SWF file originated. However, Adobe Flash Player can load data across domains if permission is granted from the server. This is accomplished by including a small crossdomain.xml file on the remote server that permits Flash to connect to services on that server.

If the above is not the issue then is your data in the same projected coordinate sytem used by the ArcGIS Online basemaps? The first thing you should do when designing the map is change the data frame coordinate system to the same one used by ArcGIS Online services, Google Maps, and Bing Maps, which is WGS 1984 Web Mercator (Auxiliary Sphere).
