jpa et problème de transactions
Bonjour,
Nouvel utilisateur de Spring (venant des ejb 3), j'essaie en vain de mettre une annotation @Transactional sur mon service. Dès que je le fais, je ne peux plus instancier mon bean :-( J'ai passé des heures dessus, sans comprendre : cela marche pourtant bien sur la couche dao...
Mon service s'appelle "taskoplanServiceImpl", ma dao "daoImpl".
Dès que je rajoute l'annotation sur le service -->
Citation:
INFO: Binding service 'TaskoplanService' to RMI registry: RegistryImpl_Stub[UnicastRef [liveRef: [endpoint:[192.168.1.3:2484](remote),objID:[0:0:0, 0]]]]
Exception in thread "main" java.lang.ClassCastException: $Proxy20 cannot be cast to be.lapinsoft.taskoplan.server.TaskoplanServiceImpl
at be.lapinsoft.taskoplan.server.TaskoServ.main(TaskoServ.java:31)
Voici le fichier xml de config de spring :
