You're getting a different error from previous. The current error suggests it's looking in the incorrect location for the crystalreportviewers11 folder - the crystal_image_uri is relative to the location of the jsp, and it's going one up the path and not looking in /Treport/crystalreportviewers11.Sincerely,Ted Ueda

You're still missing jar files. That class should be in rascore.jarSincerely,Ted Ueda

You may have mixed jar files from both versions. I'd recommend cleaning out all version 10 jars and the crystalreportviewers10 folder from your app, and copying anew version XI jars and crystalreportviewers11 folder.Sincerely,Ted Ueda
