Je ne sais pas du tout comment faire pour corriger cette erreur.

Merci

Bonjour,

Caused by: java.lang.NoClassDefFoundError: net/sf/cglib/proxy/Enhancer

Il faut que le jar qui contient net.sf.cglib.proxy.Enhancer soit dans le classpath de ton application (Dossier lib du serveur, ou WEB-INF/lib ou autres possibilités)

[bb_esca]

J'ai vérifié le jar est bien présent et c bien la bonne version.

[Mathieu.J]

Il est également possible que la classe net.sf.cglib.proxy.Enhancer ai besoin de dépendances vers d'autres jar qui eux ne sont pas dans ton classpath.

[bb_esca]

Merci pour tes reponses. J'ai trouvé c t un problème de librairie. Je n'avais pas la bonne librairie pour cglib.
