Chemin vers un fichier source ClassNotFoundException

**stc074** · 30/07/2019, 16h34

Bonjour, j'ai un projet d'appli Web sous tomcat j'essaie de mettre un custom Real dans le context.xml dans lequel je renseigne la classe à utiliser :

Code XML :

Sélectionner tout - Visualiser dans une fenêtre à part

4
<?xml version="1.0" encoding="UTF-8"?>
<Context path="">
    <Realm className ="com.directory.MyRealm"/>
</Context>

d'un autre coté j'ai mis mon fichier MyRealm.java dans le package com.directory (Netbeans) :
Nom : netbeans.png
Affichages : 170
Taille : 40,6 Ko

mais j'ai cette erreur dans les log :

Merci

Ta classe est-elle bien compilé ?

Le fichier MyRealm.class est bien plus important que le fichier MyRealm.java à l'éxécution

**stc074** · 01/08/2019, 15h50

Depuis j'ai essayé de compilé a part ma classe elle se trouve dans un jar avec le chemin com.myrealm.MyRealm, j'ai ajouté le jar à la main mais toujours la meme erreur :

Sinon je suis revenu a la première version (le fichier MyRealm dans le dossier de classe) et en effet même quand je fait un clean and build le fichier MyRealm.class n'est pas généré, je me demande bien pourquoi j'ai aucun message d'erreur.
Merci.

Bonjour,
Finalement il semblerait que le context.xml est propre à l'environnement de netbeans et que les jar ajouté au projet jee soient complètement indépendant de celui-ci. j'ai donc compilé ma classe dans un projet à part fait un build de ce projet (avec dépendances) et copié le jar dans le dossier $CATALINA_HOME/lib de tomcat, j'ai relancé tomcat puis j'ai exécuté mon autre projet (dans lequel se trouve la déclaration <Realm>) et là ça fonctionne bien.
