After started using proxy to secure all my map services and print widget not working anymore. It shows error message "esriJobFailed" and on server log will show "Error executing tool. Layer "Parcel":Failed to create layer from service at . . .". I used different taskurl to test it and all get the same error message - 1) Used print service with the credentials for the secure service from this site: http://resources.arcgis.com/en/help/...00005q3000000/ for my new 2) Used default Export Web Map Task from ArcGIS Server(http://xxx/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task).
Besides that, I used fiddler & HttpFox to monitor the traffic. From HttpFox content got this ({"jobId":"j81442677e2c24d0a94639ff12ea5157b","jobStatus":"esriJobFailed","messages":[{"type":"esriJobMessageTypeInformative","description":"Submitted."},{"type":"esriJobMessageTypeInformative","description":"Executing..."},{"type":"esriJobMessageTypeError","description":"Failed."}]}) If open map services to public (no secure) then print widget start working again. All other widget all running correctly for setting proxy to true on xml (<useproxy>true</useproxy>).
Does anyone know how to solve this problem with secure services? Thank you.
