Print widget - Export web Map Error.

Hi all,

Iam using Export web map task url (custom layouts). Iam getting this error while printing ESRI online base maps along with my local services.

Layer "World Aerial": Unable to connect to map server at http://server.arcgisonline.com/ArcGI...gery/MapServer. Failed to execute (ExportWebMap). Failed to execute (Export Web Map).

I have set the proxy url also.

It happens the same vice versa also. i.e if i use ESRI export web map task url iam unable to print my local services.
Kindly advise what has to be done.

thanks.
