Answer 1

I could not paste code into the comment. Try the following HQL:

from Etudinat where Nom = 'xxxx'

Even better, pass the username as a parameter.

Per OP request, code snippet based on the comments:

    Query q = hibernateSession.createQuery("from Etudinat where Nom = :username");
q.setParameter("username", xxxx);       
Etudinat e = q.uniqueResult();
