tuto débuttant hibernate + maven2

**natoine** · 19/02/2010, 09h30

J'essaye désespérement de faire le tuto de base Hibernate http://docs.jboss.org/hibernate/stab.../tutorial.html
Je code sous eclipse avec le plugin m2eclipse.

J'en suis au point : 1.1.7. Loading and storing objects
je tape mvn exec:java -Dexec.mainClass="org.hibernate.tutorial.EventManager" -Dexec.args="store"
Et j'ai une erreur alors je tape la même chose -e pour voir l'erreur :

Code :

Le fichier hibernate.cfg.xml est dans src/main/resources

Mon pom.xml, dés fois que ce serait un problème de version dans une dépendance :

J'ai reprie le tuto à zéro.
J'ai fait un projet dans m2eclipse sans m'appuyer sur un pom existant.
J'ai refait le pom avec les bonnes dépendances, ce qui donne ça :

La commande mvn exec:java -Dexec.mainClass="org.hibernate.tutorial.EventManager" -Dexec.args="store"

Bon ok.
J'ai éteind le serveur hsql entre temps.

Il n'empêche qu'en lançant les deux dans deux shells, j'obtiens sur l'un :

**natoine** · 23/02/2010, 21h31

hum oui bon d'accord, je les enchaîne là.
Donc j'ai recompilé le projet.
Du coup ça marche mieux, sauf que hibernate ne trouve pas le fichier hibernate.cfg.xml

**natoine** · 23/02/2010, 22h11

Aha !
Donc si je mets le fichier hibernate.cfg.xml dans le dossier src/main/ressources c'est bon, il est trouvé.
Par contre, c'est le fichier org/hibernate/tutorial/domain/Event.hbm.xml qui n'est pas trouvé

J'en peux plus.
C'est quoi ce tuto qui dit que la moitié des infos...

**natoine** · 23/02/2010, 23h30

En gros mon problème c'est que en créant le jar, maven ne copie pas les fichier .hbm.xml.
Ils devraient être associés à leurs .class respectifs.
