erreur : There is no Action mapped for namespace [/] and action name
Bonjour,
Je suis un tuto sur struts2 (tuto ici) mais je rencontre pas mal de problèmes.
L'exercice que je souhaite reproduire affiche une page avec deux liens. "Espagnol" ou "anglais" et lorsque l'on clique dessus on est censé voir une page en espagnol ou en anglais... mais lorsque je clique sur un lien, j'obtiens le message d'erreur suivant :
Code:
There is no Action mapped for namespace [/] and action name [HelloWorld] associated with context path [/essai_struts2_01].
Donc j'ai vu plusieurs sites qui traitent le problème mais cela ne m'a pas aidé à le résoudre.
Voici une copie d'écran de mon projet:
