Bonjour, 
je suis à la recherche d'une solution de mon problème: 
j'ai crée tout les modèles et ses relations avec tout les injection de dépendances... d'une application spring Maven et j'ai testé mon application pour la création de sa BD, le class de teste est: 

package org.gestion.bp.test;

import org.gestion.bp.entities.Client;
import org.gestion.bp.metier.IBanqueMetier;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {

	public static void main(String[] args) {
		ClassPathXmlApplicationContext context=
				 new ClassPathXmlApplicationContext(new String[]{"applicationContext.xml"});
				IBanqueMetier metier=(IBanqueMetier) context.getBean("metier");
				metier.addClient(new Client("C1", "Ad1"));
				metier.addClient(new Client("C2", "Ad2"));

	}

}

Bonjour.

Le message est pourtant clair : java.io.FileNotFoundException: class path resource [classpath* :META-INF/persistence.xml] cannot be opened because it does not exist

Bonjour,

J'ai le même problème, as tu résolu ?

Dans mon cas j'ai l'erreur sous netBeans car j'ai due importer le projet depuis svn pour faire des tests mais à l'origine, le projet a été fait sous éclipse où il fonctionne bien.

Bonjour,

C'est peux-être l'espace.

Au lieu de 

<value>classpath* :META-INF/persistence.xml</value>

essaye ça

<value>classpath*:META-INF/persistence.xml</value>

Bonsoir aucune nouvelle apropos .

Le fichier xml n'existe pas dans Classpath*:WEB-INF/persistence.xml

Salut,

Je suis le même tuto et je suis tombée sur la même erreur. Pour la corriger, il faut créer le ficher sous "src/main/sources" et non META-INF.

je suis le meme tuto aussi mais il montre qu'il y a java.lang.NullPointerException comme ci-dessous
