Why are these services not showing?

[TimothyGoddard]

I have a flex viewer working now that both returns services on my arcgis server machine and some from the ArcGIS online servers.

I want to add some from here:

http://www.imap.maryland.gov/portal/services.asp

There list of services has a mapserver url that says it is for Flex as they build a lot of applications on the flex architecture.

I have failed to find info on the site other than connecting with Arcmap or arcexplorer.  When i try to connect by placing the flex url in my config.xml file no data shows up but the service is listed in my TOC.  Any ideas?  IS my Crossdomain file open enough for this third location.  Is there some special arrangement that is need from MAryland.  I have an inquiry into their folks but am wondering if it is just a technical thing that i am missing when i try to set it up or if it is some aspect from their side and im just not seeing it documented.  I tried 3 or 4 of there services and had no luck with any of them.

Any idea or suggestions.  If somebody could see if they can get it to work to verify if it is me or them, I would appreciate it unless someone from there is on this forum in which case i would like to talk with you. 

Thank you.

Tim,

   The connection to there server for flex would be the same as the ArcCatalog connection URL but add "Rest".

TIm, how are you trying to access it? Two common mistakes are not specifying the correct layer type and/or incorrect URL (like forgetting the "rest").

If as a basemap or operational layer, then something like this should work:

    <layer label="Demographics" type="dynamic" visible="true" 
        url="http://mdimap.towson.edu/ArcGIS/rest/services/Biota/MD.State.BayOysters/MapServer"/>
