[Displaytag] Problème d'installation

**kanako** · 05/05/2015, 11h08

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

ma class jps :

Code :

C:\Users\Documents\NetBeansProjects\GestionClient\nbproject\build-impl.xml:936: Java returned: 1

J'ai un message en rouge qui s'affiche mais je ne suis pas sure que cela soit une erreur :

Note: C:\Users\Documents\NetBeansProjects\GestionClient\build\generated\src\org\apache\jsp\Gestion_005fClients_005fdisplaytag_jsp.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

Merci pour votre aide !!
