Erreur "javax.el.PropertyNotFoundException"
Bonjour,
je ne sais pas si c'est ici que je dois poster cette question mais comme problème désigne la servlet jsp, je me demandais si vous m'apportez vos lumières.
juste pour préciser, j'ai quasi la même chose pour une autre entité quizz, et je ne rencontre pas ce genre de problème
j'ai essayé de lancer la requête plus simple
Code:
1
2
3
| public List<Question> getAllQuestion() {
return em.createQuery("select q from Question q").getResultList();
} |
juste pour afficher la liste des question et j'ai une erreur :
