[Displaytag] Problème d'installation
Bonjour tout le monde,
après 3 jours de recherche je me suis enfin décidé à vous soliciter afin d'avoir un peu d'aide.
J'essaye de faire fonctionner la librairie displaytag en vain...
J'ai donc télécharger la displaytag 1.2.
Dans mon dossier WEB-INF j'y ai mi :
commons-logging
commons-lang
commons-collections
commons-beanutils
log4j
