Erreur "There is no Action mapped "
Bonjour, Je suis débutant sur le Struts, j'ai trouver un tutoriel sympa, http://www.roseindia.net/struts/struts2/index.shtml
Il me permet de créer des projets struts en me guidant pas à pas, sauf que je bloc sur mon premier exemple (Hello World) et même en le comparant à la solution je n'arrive pas à régler le problème, le message d'erreur est le suivant :
Citation:
