@Marianol -- the following Jaspersoft community article explains that the bundle install can be done as non-root, and has specific instructions to do so [http://community.jaspersoft.com/wiki/install-bundled-package-jasperreports-server-and-run-application-non-root-user]. We have installed the bundle as non-root successfully -- as one user -- but with a different user we are getting the same error as shown above. Still investigating. ==> Update: Now all non-root users work correctly when installing the bundle (as of Dec 26). No special permissions or sudo are required. See update comment below for more info.
