Ouhlalala ya du code qui se fait repomper la. J'ai vu ce code il y a 3h avec un autre pseudo (celui de gentil) . Soit repompage soit 2 pseudos,

Sinon bref,
Ton erreur est qu'il n'arrive pas à se connecter à ta base.

Vérifie :

<property name="connection.username">root</property>
<property name="connection.password"></property>
<property name="connection.url">jdbc:mysql://localhost:3306/base1</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>

Ton user, ton password, ton url, et que ton driver soit bien dans le classpath.

Ce qui est bizarre c'est que dans la stacktrace il y a marquer qu'il a essayer de se connecter en utilisant un password de 4 caractere et que tu n'en ais pas dans ta config;

En fait, j'ai trouvé le probleme..

je passais pa le bonne class ( qui contient les getter et les setter ) dans le fichier de mapping, du coup il trouve
pa le getter du nom .

voila, merci pour vautre aide commeme .

 Session session = HibernateUtil.currentSession();
 Transaction tx = session.beginTransaction();
 List list = session.find("from TContact where nom like '%t'");
	 Iterator it = list.iterator();
	 while(it.hasNext())
	 {
	   TContactId contact = (TContactId)it.next();
	   System.out.println(contact.getNom());
	 }
 HibernateUtil.closeSession();
 HibernateUtil.closeSession();

en fait il reconnais pa la methode find de la slass session: session.find("string");
donc svp si vs pouvez m'aider, j'ai besoin de fair une selection de la base de données et je trouve pa garnd chose sur internet .
merci d'avance

**maxf1** · 13/04/2007, 10h31

C'est pas parce que tu as décidé que tu voulais faire un find que la méthode doit s'apeller find.

Tient voila une chose très importante dont tu dois te servir.
IL existe le meme type de documentation pour toutes les classes Java (normalement).

http://www.hibernate.org/hib_docs/v3...e/Session.html

**sissa_87** · 13/04/2007, 10h39

merci pr ta réponse,
mais sinn comment on fait une selection si on utilise pa find??
