Derby serveur et hibernate
Bonjour,
J'ai un problème sur l'utilisation d'hibernate avec derby. Avant j'ai utilise hibernate avec postgresql maintenant je concerve le meme model de données mais avec le gestionnaire Derby en mode serveur. j'ai fait quelque changement sur hibernate.cfg.xml et aussi sur le fichier xml du mapping de la base.
voici des extrait de mes fichiers :
<property name="connection.driver_class">org.apache.derby.jdbc.ClientDriver</property>
<property name="connection.url">xxxxxx;create=true</property>
<property name="connection.username">xxxxx</property>
<property name="connection.password">xxxxx</property>
<property name="dialect"> org.hibernate.dialect.DerbyDialect</property>
et
le fichier hbm
<class
name="Osextension"
table="osextension"
>
<id
name="Id"
type="integer"
column="id"
>
<generator class="native"/>
</id>
et je recois tj le msg d'errur suivant
