nested exception is java.lang.IncompatibleClassChangeError: Implementing class

Bonjour tout le monde,

Voila j'ai un projet en construction qui pour le moment utilise Spring et Hibernate.

Je veux tester simplement si mon architecture fonctionne via un test unitaire simple qui verifie si le login et le password son correcte par rapport à se qu'il y a en base de donnée ( mysql ).

Donc en gros voila mon test unitaire :

import java.util.ArrayList;
import java.util.Collection;
 
import home.my.service.IUserManager;
import junit.framework.TestCase;
 
import org.junit.Test;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;
 
 
public class UserTest extends TestCase {
 
	@Test
	public void testCheckLogin(){
 
		XmlBeanFactory bf = new XmlBeanFactory(new ClassPathResource("spring-config.xml"));
		IUserManager user = (IUserManager) bf.getBean("userManager");
		assertTrue(true);
		assertTrue(user.checkLogin("romain", "13041983"));
	}
}

voila mon fichier de configuration spring : spring-config.xml

</beans>

pour le reste le fichier de configuration hibernate tout ça tout ça je pense que c'est ok. Je vous met donc la trace le log que je reçoit a l'execution du test :

En gros ce que j'ai pu constater c'est cette erreur :

Code:

java.lang.IncompatibleClassChangeError: Implementing class

et la je comprends pas... qu'est ce qui deconne ???????

probablement incompatibilité de JARs…

vérifiez que les versions des JARs que vous utilisez sont compatibles entre elles et avec votre JVM…

etrange j'ai regardé un peu mais rien ne semble de pas fonctionner ensemble.

j'ai un jdk 1.6 et jre 6
avec donc hibernate 3
et un spring 3.03

Oui donc petite correction, oui en recuperant l'ensemble des librairies d'un projet qui fonctionne la plus de soucis )). Bon parcontre d'autre soucis mais c'est autre chose ))).

Merci à toi...

La compilation a vraissemblablement été effectuée avec une version de la classe org.springframework.orm.hibernate3.LocalSessionFactoryBean alors qu'à l'execution de ton test u, une autre version de la classe est utilisée.
T'aurais pas deux versions de Spring dans ton classpath ?

oui en effet il y en a une 1.2.6 et une autre 3.0.3.
Pour le moment j'ai gardé la version 1.2.6

Je tatonne encore sur certain point de la session factory, des que c'est stabiliser je vais faire en sorte qu'il n'y ai qu'une librairie spring )))

Merci à vous.
