from rest:
http://serverapp:8399/arcgis/rest/services/HranicaSR2/MapServer can you export to jpeg?

DanielTuracek · ‎10-20-2010

i give you know tomorow , because its our local test arcgis server, so i havent connection now.
There is probably problem with my service, i tried to get my service on display with more codes wich works fine for Arcgis example servers, but for my service i get just blank page.
I tried service for tiled map and dynamic too. i tried to import coordinate system from example files. but still nothing

thank you
and tomorow i will tell you more

First off, I want to mention that your code would've been easier to read and analyze with the forum's

 tags instead of what you used.

Anyway, one glaring problem that I see is that you're using the ArcGIS JS API version 1.6. This may be a deliberate choice of yours, but there is a much newer and better version out (v2.1). If you have mistakingly been using 1.6, then change <script type="text/javascript" src="http://serverapi.arcgisonline.com/jsapi/arcgis/?v=1.6"></script>
 to <script type="text/javascript" src="http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.1"></script> 

and also change the external CSS from <link rel="stylesheet" type="text/css" href="http://serverapi.arcgisonline.com/jsapi/arcgis/1.6/js/dojo/dijit/themes/tundra/tundra.css">

to
<link rel="stylesheet" type="text/css" href="http://serverapi.arcgisonline.com/jsapi/arcgis/2.1/js/dojo/dijit/themes/claro/claro.css">


Other than that, I don't see why it shouldn't work. You should definitely look into ciava.at's suggestion, as I also think your use of custom imageParameters (set to JPEG) is why it's not rendering.

Good luck!

You code is OK, your URL is wrong. You're not accessing the rest endpoint of your service.

Your URL is:

http://serverapp:8399/arcgis/services/HranicaSR2/MapServer

Should be something like:

http://serverapp:8399/arcgis/rest/services/HranicaSR2/MapServer

Ok
I tried everything but no result.
Its seems like our rest doesnt work right way, because i copy the URL links directly from service manager, and there is no any rest middle of URL.
So i dont know.

javanse_jongense,

ArcGIS Server supports per default - and beside others - two standard interfaces for every service: SOAP and REST. While the Service Manager and all of the Web-ADF, as the ArcGIS Desktop apps, consume ArcGIS Server services over SOAP, the Web-API like JS, Silverlight, Flex consume the AGS Services over REST.

The difference between the URLs to the services is the rest part, as I have said before.

Please take a look at the documentation of the JS API: http://help.arcgis.com/en/webapi/javascript/arcgis/help/jshelp_start.htm#jshelp/ags_overview.htm

Especially take a look at your Services Directory at: http://serverapp:8399/arcgis/rest/ or any other service directory like The ArcGIS Online Services Directory.

Hope that helps.
