Gestion de transaction - atomique
J'ai le problèmes suivant. Je n'arrive pas a rendre l'exécution des méthodes de mes services atomique
j'ai configurer les transactions comme cela avec SPRING + HIBERNATE + GenericDao (du site d'IBM)
NB: si je met tout en read only j'ai bien une erreur et pas d'enregistrement en base donc je pense que l'aop fonctionne.

Je voudrais un rollback sur le premier create mais en fait il n'y en a pas.
Je ne sais pas comment faire.
