jgroups-2.2.7.jar
jta.jar
commons-logging-1.0.4.jar
asm-attrs.jar
dom4j-1.6.1.jar
antlr-2.7-5H3.jar
cglib-2.1.2.jar
asm.jar

Qu'est ce que je n'ai pas compris ? Merci de bien vouloir m'aider...

Mon erreur vient du nom du Dialect dans le fichier de config d'hibernate :

il faut mettre org.hibernate.dialect.Oracle9Dialect et non

net.sf.hibernate.dialect.Oracle9Dialect

Attention aussi à la version du driver :

ojdbc14.jar pour un >= JDK 1.4
et classes12.zip pour un JDK inférieur
