Managed Bean exception chargement de la page
Bonjour
Je souhaite créer un site webb JEE avec les frameworks Spring 2.5.6 JSF1.2 Hibernate 3.
Le problème est lorsque je veux vérifier l'injection d'un managed bean simple via un message dans une JSP j'obtiens une exception.
Code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
