[Hibernate 4.3] erreur de syntaxe HQL

Bonjour, j'essaie d'implémenter hibernate sur une de mes applis web, je l'ai fait via netbeans, par contre netbeans n'a pas voulu me générer mes Classes/fichier hbm avec son outil, j'ai donc tout fait à la main
Je test une requête HQL

Code:

from users

J'ai cette erreur :

je pense pas que la syntaxe soit mauvaise, il doit y avoir un autre problème.
