J'ajoute que quand j'eceute ce class loader hors du projet Eclipse RCP cela fonctionne parfaitement.
J'ai bien intégré toutes les dépendances, ainsi que le driver Oracle.

Bonjour.
Apparamment, c'est un problème causé par les conventions de nommage d'eclipse RCP des bundles (le préfixe numérique comme //57/, etc.), mais je n'en suis pas sur vu que je n'ai jamais fait d'eclipse RCP.

Ceci pourrait peut être t'aider:
:arrow: http://forum.springframework.org/showthread.php?t=22234

Bonne chance.

P.S.: Tu n'as pas besoin d'un load time weaver avec Hibernate.

Bon a priori c'est un bug reconnu mais toujours pas solutionné qui empeche de faire fonctionner
Eclipse RCP +Spring +Jpa +Hibernate
Car ArchiveBrowser attend un protocole que le bundle eclipse n'est pas capable de lui fournir correctement.

Nous allons essayer de remplacer Hibernate par TopLink ...

djo.mos --> P.S.: Tu n'as pas besoin d'un load time weaver avec Hibernate.
que veux dire cette dernière remarque ?

Dans ton fichier de configuration de Spring, tu as déclaré un load time weaver:
Code:

1 2 3 4 5 
Mais maintenant que je le dis, je viens de remarquer q'il est commenté :aie:

Donc, en utilisant hibernate comme implémentation JPA, on n'a pas besoin du Load Time Weaver (il ne faut pas déclarer ce bloc dans le ficher de config de spring).
Par contre, lorsque tu utilises Toplink, il t'en faudra un.

Resolu pour moi avec hibernate

En effet le protocole bundleresource n est pas reconnu
j ai resolu mon probleme en surchargant une classe, c est pas top classe mais ca fonctionne en attendant que le bug soit regle

donc : New Class -> package = org.jboss.util.file, ClassName = ArchiveBrowser et colle le bout de code ci dessous.

(tips:sur eclipse 3.3 tu copie le code et colle en cliquant sur le src, ca cree tous seul la classe)

en creant org.jboss.util.file.ArchiveBrowser on surcharge l api fournit par jboss ....

enjoy,
