I just experience an issue with a fresh install of Jasper Server 6.3 and i set up the administration jasper integration but there was no spectrum folder and no canned reports. I finally spoke with CA Services Consultant Alan Le and he knew of the bug and we fixed it in less than 2 seconds! If you experience this issue - I attached a picture of the repository in the jasper console. Go back to the administration page in spectrum and to the jasper integration and remove the user and password - then retype them both back in and click save -- Everything is fine.
