configuration jpa tutoriel M. Mahé

Version imprimable

Bonjour,

je suis en train de suivre le tutoriel de M. Mahé.

La tache ant DLL ne se deroule pas normalement. une exception de type nosuchmethoderror est levée.
La classe concernée est AnnotationConfiguration.

Les jars que j'ai tout d'abord utilisée sont ceux proposée par le tutoriel.
Ensuite je me sui dit qu'il peut y avoir un probleme et j'ai telechargé les différents jar de hibernate ( core, annotations, tools et entitymanager) sur l le site officiel en faisant bien attention de respecter la matrice de compatibilité.

voici l'erreur

Effectivement, je ne vois pas la method concernée dans les sources du zip hibernate annotation.

Pour info j'utilise
une jdk 1.6
eclipse 3.3.2

Quoi d'autres ...

La tache ant DLL ne se deroule pas normalement. une exception de type nosuchmethoderror est levée.

d'apres la définition de : NoSuchMethodError , celle-ci est lancée
quand on utilise des JARs incompatibles (des virsions incompatibles)

verifies les jar utilisés..

phantomass

Comme l'indique ton message d'erreur, as tu dans ton classpath hibernate-entity-manager.jar ?

Comme l'indique ton message d'erreur, as tu dans ton classpath hibernate-entity-manager.jar ?

Est ce que c'est pas question d'incompatibilié entre les deux JARs :
- hibernate-tool.jar
- hibernate-entity-manager.jar

?

J'ai bien dans mon classpath le entity-manager.

Comment verifier le probleme de compatibilité ??

g laissé tomber la tache ant (Pour info elle générait un script SQL et créait la structure de la base (apparement en se basant sur les annotations)) et je suis directement passé à l'insertion en base.

Au début, des erreurs anologues se sont déclenchées. Mais en remplacant les jars hibernate annotations et entity manager, j'ai pu inserer des lignes dans ma table.

Après ce succés, j'ai voulu retester la tache ant. elle ne fonctionne toujours pas.

Ce post est a moitié resolu dans le sens où je peut continuer le tutoriel. mais j'aimerais quand meme faire fonctionner cette tache et à défaut avoir des pistes du pourquoi de la chose.

voili voilà. a bientot pr d'autres pb
