J'ai une page jsp avec une connexion jdbc et en premier chargement, il montre les données avec précision, mais après il montre des tables vides, je pense que la deuxième fois il charge de la mémoire du serveur pascomment recharger la page jsp à chaque demande?
quel est le problème derrière je ne sais pas
ok voici les détails
i une servlet qui maintient la session d'un utilisateur qui se connectent, puis après avoir créé la session, le servlet redirige l'utilisateur vers une page de vue qui est une page jsp et affiche la enregistrements existants dans DB
lorsque le SERV let redirige la page que le jsp peut montrer les enregistrements mais quand j'accède à cette page de n'importe quelle autre page html il est incapable d'afficher les enregistrements ici est le code pour la page de jsp à voir.

lire votre question et demandez-vous si vous fournissez des informations suffisantes. – Bozho
* il montre des tables vides * - pourrait être une variété de problèmes - a-t-il perdu la connectivité DB - y at-il des erreurs dans les journaux - vérifier tout cela et poster plus de détails. – JoseK
ok je pense maintenant que j'ai fourni assez d'informations pour répondre à cette question plz faites moi savoir si un important est manquant @Bozho @JoseK – Badr
