ArcGISDynamicMapServiceLayer Will not display

PaulLang — Fri, 21 Jan 2011 19:25:47 GMT

For some reason after moving to 10.0 ArcGISDynamicMapServiceLayers will not display.
ArcGISTiledMapServiceLayer work fine, any clue?

Paul,

You are not giving enough info... Are you saying you have an existing custom Flex API app that is using the same ArcGISDynamicMapServices, same url and now that you upgraded to Server 10 they don't work? Have you gone to the REST Service directory and tested that the upgrade went OK and you can see them listed there and preview them?

Just taking ESRI samples and putting my services instead of ESRI services. The Tiled services work fine, but not the dynamic.
Flex Builder 4.0

Tiled:
http://gcgis/ArcGIS/rest/services/Imagery/Orthos2009/MapServer
Dynamic:
http://gcgis/ArcGIS/rest/services/Daily/TestService/MapServer

<esri:ArcGISTiledMapServiceLayer url="http://gcgis/ArcGIS/rest/services/Imagery/Orthos2009/MapServer"/>

When you go to the urls of your dynamic services, do the links to "ArcGIS JavaScript" and "Export Map" work OK?

Re: ArcGISDynamicMapServiceLayer Will not display

ArcGIS JavaScript Link results:

Server Error
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

Export Map link works, but no image displayed.

Paul,

Delete the map service and publish it again. There are sometimes issues with upgrading that corrupts map services.

I did as suggested, but same result.
However I changed the service to tiled service and build a cache, published and it works.
ArcGISDynamicMapServiceLayer still not working...

Tiled:
http://gcgis/ArcGIS/rest/services/Daily/TestService/MapServer
Dynamic:
http://gcgis/ArcGIS/rest/services/Daily/Dynamic/MapServer

All map services ArcGIS JavaScript Link results:

Server Error
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

Paul,

Time to call tech support!

Re: ArcGISDynamicMapServiceLayer Will not display

PaulLang — Fri, 28 Jan 2011 13:23:31 GMT

Update:
ESRI Tech support help:

ArcGIS JavaScript Link now functions correctly.
Change made:
C:\inetpub\wwwroot\ArcGIS\rest\web.config
RequireToken value changed to FALSE

<appSettings>
<add key="RequireToken" value="FALSE" />
<add key="ShortTokenTime" value="60" />
<add key="LongTokenTime" value="14400" />
<add key="TokenServiceURL" value="https://gcgis/ArcGIS/tokens/" />
<add key="TokenKey" value="bctm1563BC" />
</appSettings>

Still unable to get any ArcGISDynamicMapServiceLayer to display, have a new instance with developer support, but waiting.

Do any of you pro's know why my Flex setup will not display this:

Paul,

Kind of a silly question but do you have the Flex API swc in the libs folder of your project or have it referenced in the library path of the project?

Re: ArcGISDynamicMapServiceLayer Will not display

PaulLang — Fri, 28 Jan 2011 14:04:36 GMT

Referenced Libraries

Re: ArcGISDynamicMapServiceLayer Will not display

PaulLang — Fri, 28 Jan 2011 14:16:38 GMT

What I just discovered is this, if I reduce the size of my browser window the services will display.
Image size limits somewhere?

Re: ArcGISDynamicMapServiceLayer Will not display

RobertScheitlin__GISP — Fri, 28 Jan 2011 16:55:03 GMT

Paul,

In Flash Player 9 the limits were simple not bitmapdata above 2880x2880. Now with Flash Player 10 that is even bigger. But unless you are trying to display on a big screen TV you are unlikely to reach this limit. Have you used Fiddler or something along that line to see the request and response traffic?

IE 8
Dell 27" Monitor

From Fiddler
On expansion of window:
# Result Protocol Host URL Body Caching Content-Type Process Comments Custom
6 404 HTTP gcgis /ArcGIS/rest/services/Daily/NewDynamic/MapServer/export?transparent=true&f=image&bbox=1355582%2E4690162383%2C537488%2E0281804466%2C1368784%2E780923587%2C543439%2E9410309125&dpi=96&bboxSR=2264&size=2125%2C958&imageSR=2264&format=png8 1,245 text/html iexplore:5524

When browser window is small:
# Result Protocol Host URL Body Caching Content-Type Process Comments Custom

The Body column within Fiddler, when the value exceeds 185,000 the service goes away.

Paul,

Ok, so what resolution is your 27" monitor running at then?

Re: ArcGISDynamicMapServiceLayer Will not display

PaulLang — Mon, 31 Jan 2011 11:58:39 GMT

2560 x 1440 Landscape
I have changed to much lower, but same result.

Re: ArcGISDynamicMapServiceLayer Will not display

RobertScheitlin__GISP — Mon, 31 Jan 2011 12:20:02 GMT

Paul,

This is definitely a new one maybe tech support will get back to you soon.

Re: ArcGISDynamicMapServiceLayer Will not display

PaulLang — Mon, 31 Jan 2011 12:22:59 GMT

I just tested Fire-Fox just to see if it was an IE 8 issue, but unfortunately not.
Thanks for all your help!

This will fix it! Explains my random blank images...

From Tech Support:
Every map service's config file has <MaxImageHeight> and <MaxImageWidth> properties set to 2048 by default. You will need to modify those values to be able to generate larger maps. I think 27 inch monitors have a resolution of 2560x1440 pixels. Restarting SOM afterwards should reflect the changes. Here is more documentation on this:
