Deux problèmes pour un premier JSP simple

**Pandalex** · 05/03/2021, 12h49

Bonjour,

Je débute sur le JSP et j'ai deux problèmes que je n'arrive pas à résoudre sur un programme assez basique.

J'ai deux blocs :
- Un java+jsp pour enregistrer des données
- Un java+jsp pour afficher les données

Je charge la page :
http://localhost/test/addUf.jsp

Je remplis mes données, je clique sur ajouter.
L'insertion en base se fait et au niveau de la barre d'adresse j'aboutis sur
http://localhost/test/servletRecord

Le problème c'est au moment où j'arrive sur ce servlet Record je tombe en erreur que je ne comprend pas :

Niveau jar j'ai:
