Error when using print service on dynamic layer

[GerardoArmendariz]

I am trying to get my application to use the new PrintTask.

When I try to print the current extent with a ArcGISDynamicMapServiceLayer, I get the following error:

Unable to complete operation.

Anyone out there who have successfully used the PrintTask with a dynamic layer?

We've checked the firewall for any problems and did not find anything wrong.  Would it be possible that there would be a problem with the way we setup the web adaptor?

The JSON was build based on an example in the forum.  I don't think that's the problems since it seems to be working with ESRI's export service. 

Is it possible that your export service isn't able to connect to http://apps.tucson.ars.ag.gov/arcgis/rest/services/dap/DAPSites/MapServer? Maybe a DNS or firewall issue?

I'm curios where this JSON is coming from too since it doesn't look like it's from the PrintTask. I don't think that's the issue though since it does work from Esri hosted export services.

Not sure if it is related, but I find it intersting that your print task or does not show in your Rest Services Directory.<http://apps.tucson.ars.ag.gov:6080/arcgis/rest/services>  In fact, Idon't see any of the folders in there either.

If you go to the task itself, it is there, but not listed in the directory structure as ESRI's is here: <http://servicesbeta4.esri.com/arcgis/rest/services> where you "see" the folder/task listed under every level.

It turns out that my problem was related to the "hosts" file ( under Windows\System32\drivers\etc )

My server was not able to connect to the server's URL internally.

To solve it, I modified the mapping in the hosts file to this:

server_ip_address        localhost  SOURCESERVERNAME  SOURCESERVERURL

It now works!

I have the same issue,well sort of. Using flashbuilder 4.6 i see my layers on the map but when I use the print widget it says unable to connect. Using ESRI services it works fine . If I use application builder it works fine for both my services and ESRI services but I need more advanced printing than application builder allows.  What does application builder do different than the source code as far as connecting to services???

can you post an example of your hosts file?
