erreur lors de l'injection de l'EntityManagerFactory

**al3alwa** · 10/02/2009, 11h44

Bonjour,

sur un petit projet java SE, j'essaie de travailler avec spring avec hibernate JPA.
Pour faire j'ai voulu injecté l'EntityManagerFactory directement avec Spring, sauf qu'il me retourne une exception

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

merci d'avance de vos suggestions

Salut,
Ca a l'air de venir d'un problème de versions d'ASM/CGLib.
Tu pourrais nous lister ce que contient ton classpath ? Entre temps, essaies d'utiliser cglib_nodep si tu utilises le cglib ordinaire.

**al3alwa** · 11/02/2009, 09h52

merci pour ta réponce

ta raison, l'erreur venait de l'incompatibilité de CGLIB et ASM dans la configuration par defaut de netbeans sur un projet utilisant Spring 2.5 et Hibernate 3. J'ai remplacé les jar ajoutés par netbeans avec ceux fournis par un exemple que tu as mis sur le net

et la ça marche

encore une fois merci
