this doesn't work either. i'm getting quite frustrated now, because 1 namequery works, but the others don't. the one that works is: | @NamedQuery(name = "User.doLogin", query = "SELECT object(u) FROM User u WHERE u.naam = :uname AND u.password = :password") | and on the other entities the namedqueries work also. are you able to get the problem from the stacktrace i posted in the first post? many thanks!
