Bonjour


j'ai cette erreur en utilisant hibernate

Exception in thread "main" java.lang.NoClassDefFoundError: org/dom4j/DocumentException
at fr.classe.HibernateUtil.main(HibernateUtil.java:16)

voici mon code "main"

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

package fr.classe;   import org.hibernate.HibernateException; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.cfg.Configuration;         public class HibernateUtil {   public static void main(String[] args) throws HibernateException {   SessionFactory factory = new Configuration().configure().buildSessionFactory(); Session session = factory.openSession(); Transaction tc = session.beginTransaction() ; FournisseurId fourn1 = new FournisseurId(); fourn1.setAdressefourni("essai"); fourn1.setNomfourni("essai"); session.save(fourn1);   tc.commit() ; session.close(); }   }

quelqu'un pourrait me dire si j'ai pas oublié de faire quelque chose?
Merci pour vos réponses

J'ai rajouté tout les jar fourni avec hibernate
et maintenant j'ai cet énorme message d'erreur

donne un peu plus d'infos.
ton fichier de config par exemple, et le code qui te permet d'accéder à Hibernate.

voici mon fichier hibernate.cvg.xml

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory name="EssaiFactory"> <propertyname="hibernate.connection.driver_class">org.gjt.mm.mysql.Driver</property> <property name="hibernate.connection.password">azerty</property> <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hiberessai</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> </session-factory> </hibernate-configuration>

---

et mon code pour rajouter des trucs dans ma base mysql

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

package fr.classe; import org.hibernate.HibernateException; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.cfg.Configuration;   public class HibernateUtil {   public static void main(String[] args) throws HibernateException {   SessionFactory factory = new Configuration().configure().buildSessionFactory();   Session session = factory.openSession(); Transaction tc = session.beginTransaction() ; FournisseurId fourn1 = new FournisseurId(); fourn1.setAdressefourni("essai"); fourn1.setNomfourni("essai"); session.save(fourn1); tc.commit() ; session.close(); } }

---

Code:

---

<session-factory name="EssaiFactory">

---

- Si tu utilises vraiment JNDI, alors ton namespace "EssaiFactory" est introuvable (plutot louche comme nom 8O)

- Si tu n'utilises pas JNDI, alors retire l'attribut "name=....."

Regarde l'erreur :

Code:

---

1 2	Exception in thread "main" org.hibernate.MappingException: Unknown entity: fr.classe.FournisseurId

---

Tu n'as pas déclaré le mapping de FournisseurId dans ton fichier de config.

Envoyé par fr1man

Tu n'as pas déclaré le mapping de FournisseurId dans ton fichier de config.

---

Ah oui. lol. j'ai zappé l'exception et je me suis précipité sur le warn. :oops:

Enfin bon, supprime quand meme le lookup JNDI, ca fera plus propre.

On fait ca comment ?
parce que fichier .xml ont été généré automatiquement
J'ai une classe Fournisseur.java qui a été créé et FournisseurId.java
avec un Fournisseur.hbm.xml

avec ça :

Code:

---

1 2	<mapping resource="com/test/db/hbm/TonFichier.hbm.xml" />

---

En remplaçant le package et le fichier xml par les tiens.

Voici mon nouveau hibernate.cfg.xml

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.connection.driver_class">org.gjt.mm.mysql.Driver</property> <property name="hibernate.connection.password">azerty</property> <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hiberessai</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> <!-- fichiers de mapping --> <mapping resource="fr/classe/Fournisseur.hbm.xml" /> </session-factory>   </hibernate-configuration>

et eclipse me met cette erreur maintenant

Il te manque surement le asm.jar dans tes libs.

Un p'tit truc que j'ai pas bien saisi
j'ai une table mysql fournisseur
et quand hibernate à générer le .java correspondant
il m'a générer Fournisseur.java avec son hbm.xml et FournisseurId sans hbm.xml

voici le code des deux classes

Code:

Pourquoi y en a deux Fournisseur et FournisseurId, je vois pas comment par exemple rajouter un fournisseur dans ma table avec ca

il me manquait bien le asm.jar

Merci ca marche nickel maintenant
