Problème Servlet / Quartz
Bonjour,
Je dois développer un planificateur de tâches avec quartz en java sous une servlet pour qu'il puisse démarrer en même temps que le serv apache, mais il y a quelque chose qui ne va pas. Je vous montre la source.

Si vous pouviez m'aider ^^, si le plus probable vient de tomcat5.0 où directement du fichier java où encore des fichiers annexe tels que quartz.properties (sur lequel j'ai un doute sur son fonctionnement) et web.xml.
