Info Pop up Window Trouble

[DerekTokarz1]

I keep geting the error message,
"[IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032"]
http response status: 404
Fault Code: Server.Error.Request
Fault Info: HTTP request error
Fault Details: Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032"]. URL: http://rtams.org/flexviewer/widgets/InfoTemplates/CTASTATIONS.xml"

I have my files in SDE here is what my xml file looks like
<layer label="CTA Stations" type="feature" visible="true"
info="widgets/InfoTemplates/SimpleInfoWinWidget.swf"
infoconfig="widgets/InfoTemplates/CTASTATIONS.xml"
url="http://rtamsp2.ai.uic.edu:8399/arcgis/rest/services/sdeLayers/MapServer/0"/>

Any ideas?
I added the filed names to the infotemplates. Feature Access is also turned on in ServerManager.

Derek,

   Are you able to put http://rtams.org/flexviewer/widgets/InfoTemplates/CTASTATIONS.xml in your browser address bar and actually see the file?

[DerekTokarz1]

No I am not able to see it. I can see http://rtamsp2.ai.uic.edu:8399/arcgis/rest/services/sdeLayers/MapServer/0
Am I supposed to be able to .xml?

[RobertScheitlin__GISP]

Derek,

   Then that is definitely the source of your error. You have to figure out what is wrong with that url...

[DerekTokarz1]

Why does it have to be a URL if it is directed to an .xml file located in the widgets folder?
infoconfig="widgets/InfoTemplates/CTASTATIONS.xml

Thanks for the help by the way.

[RobertScheitlin__GISP]

Derek,

  The error that you are getting has to do with the file not being there. Flex is 100% case sensitive so could that be your issue in the path to your xml file?

in config.xml Try to write URL without specification of number of layer in rest service
url="http://rtamsp2.ai.uic.edu:8399/arcgis/rest/services/sdeLayers/MapServer"/>
