Netbeans 6.8, JPA/Hibernate, Ant, MySQL

Bonjour

J'essaie depuis deux jours de suivre le tutoriel JPA/Hibernate de Serge TAHE et j'obtiens le message suivant :

Mon environnement d'étude est le suivant : WIN XP / NetBeans 6.8 / MySQL5 / java version "1.6.0_14"

le dossier racine de mon projet : C:\NetBeansProjects\jpa01 (ne contient donc pas d'espace).

Vous trouverez en copie mon fichier build.xml et persistence.xml, l'arborescence du projet.

contenu de log4j.properties :

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

# Root logger option
log4j.rootLogger=ERROR, stdout

# Hibernate logging options (INFO only shows startup messages)
#log4j.logger.org.hibernate=DEBUG

# Log JDBC bind parameter runtime arguments
#log4j.logger.org.hibernate.type=DEBUG

Je vous suis reconnaissant d'avance de l'aide que vous voudrez bien m'accorder.

Code:

---

1 2	<property name="dialect" value="org.hibernate.dialect.MySQLDialect" />

---

->

Code:

---

1 2	<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />

---

(Le stack trace est pourtant clair…
org.hibernate.HibernateException: The dialect was not set. Set the property hibernate.dialect.
)

Je n'arrive toujours pas à générer le fichier schema.sql.
Y a t'il un tag Ant pour créer le fichier avant d'exécuter
<hbm2ddl drop="true" create="true" export="false" outputfilename="ddl/schema.sql"
delimiter=";" format="true" />

le repertoire ddl existe bel et bien, mais ci-dessous l'erreur :

1 errors occurred while performing <hbm2ddl>.

Peut être que la réponse n'est pas compliquée mais je ne la trouve pas. Merci encore de ton aide.

Effectivement j'ai changé de repertoire et ça marche. C'étias effectivemt un problème de droit d'écriture.:)
