Thank you for your reply, I was looking for an "automatic" solution ( I mean, first installation already working as expected without manual intervention) but your suggestion works as expected: I have modified the rights of the Ad-hoc components and Topics folders to "Execute Only", moved all ad-hoc views into the Topic folder and created a Report folder with read-only rights where I moved all the reports. When "read-only" users now login to JasperServer, they can see only "Reports", and even if they modify the filter on the Library page to show "ad-hoc views" they do not see anything. Meaning that I have to prepare a manual for the "first parameterizazion" for my customers. Anyway, very good! Thanks a lot and have a wonderful day. GB
