Une exception dans le tutorial
Bonjour,
J'essaie de découvrir Spring à traver le tutorial 'step by step' de Spring mvc sauf qu'à la fin du chapitre 4, la page http://127.0.0.1:8080/springapp/priceincrease.htm genere une exception que je n'arrive toujours pas à résoudre.
Voici le contenu de la page:
