erreur HTTP 404 introuvable dans struts2.0. mais la console ne montre aucune erreur

Question

Je suis en train de créer une application web dynamique struts mais l'erreur suivante est affichée dans le navigateur web

The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

général, cette erreur se poseraient en raison de bibliothèques manquantes ou des pages et je les diagnostiquerait en regardant la console. Mais cette fois, la console ne montre aucun type d'erreur.

est ici la sortie de la console:

Erreur:

J'ai essayé les solutions données sur des questions similaires, mais sans résultat.

Answer 1

Vous devez pas pages JSP accès directement, plus ils sont plus stockés dans WEB-INF et ne sont pas accessibles par le navigateur.

La solution consiste à créer un dossier nommé WEB-INF/content et à y placer des fichiers, puis d'utiliser un convention plugin pour créer des mappages d'action et configurer les résultats. Ce nom de dossier est utilisé par convention où Struts recherche des ressources pour les résultats.

Le plugin convention permet pages d'accès sous WEB-INF directement, mais vous pouvez éviter cela en Deny direct access to JSP files in Struts2 with Naming Convention plugin.

---

Une autre point est que:

Convention plugin creates configuration from all JSPs there. So if you have do-something.jsp under result path you can use /do-something in the browser to return this actionless result.
