[EJB3 Entity] MySQL + Jboss => erreur de syntaxe SQL

Bonjour,

Je suis en train d'écrire un prototype d'application EJB3 utilisant un session bean stateless pour authentifier un utilisateur.

L'application est crée sous netbeans6.5 , utilise JBOSS 4.2.3.GA , MySQL5 (base de donnée définie avec InnoDB)

Je précise tout de suite que j'ai bien indiqué MySQL5InnoDBDialect dans le persistence.xml.

A l'execution, la chaine eJbql ne semble pas être traduite correctement en SQL MySQL et l'application plante.

Voici des extrait de mon code:

Configuration persistence.xml
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <persistence-unit name="EJBInqasPU" transaction-type="JTA"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>java:/InqasDB</jta-data-source> <class>inqas.entities.Iusers</class> <class>inqas.entities.Ientrs</class> <exclude-unlisted-classes>true</exclude-unlisted-classes> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/> <property name="show_sql" value="true"/> </properties> </persistence-unit> </persistence>
Extrait du bean session:
Code:

1 2 3 4 5 6 7 8 9 ublic boolean isKnownUser(String userName) { Iusers iusers; String sql = "FROM Iusers i WHERE i.uskus = :uskus"; //String sql ="select uskus from iusers where uskus=:uskus" ; iusers = (Iusers) em.createQuery(sql).setParameter("uskus", userName).getSingleResult(); //String user = em.createNativeQuery(sql).setParameter("uskus", userName).getSingleResult().toString();
La Log jboss où l'on voit que le dialecte MySQL est pris en compte

Quelqu'un aurait il une petite idée de ce que j'ai loupé ? Ca fait 2 jours que je tourne et retourne le code dans tous les sens et parcours internet sans trouver une info utile sur ce sujet.

quoi que je fasse dans ma chaine SQL (instruction complete ou partielle) j'ai ceci dans l'erreur '.iusers iusers0_ where iusers0_.USKUS='OC'' . Visiblement la conversion vers le SQL de MySQL ne se fait pas ou mal....:roll:

De plus les exemples utilisant MySQL avec Jboss ne sont pas légions...

Si j'utilise un CreateNativeQuery , bien sur tout fonctionne (mais mon but n'est pas d'utiliser du query natif dans le code ;) )
