Code between sessionFactory.openSession() and session.close():

I use this hibernateUtil class:

Code:

package soup.metier;

import net.sf.hibernate.*;
import net.sf.hibernate.cfg.*;

public class HibernateUtil {

 private static final SessionFactory sessionFactory;

 static {
   try {
   // Crée la SessionFactory
   sessionFactory =
    new Configuration().configure().buildSessionFactory();
   } catch (HibernateException ex) {
   throw new RuntimeException("Problème de configuration : "
   + ex.getMessage(), ex);
   }
   }

 public static final ThreadLocal session = new ThreadLocal();

 public static Session currentSession()
      throws HibernateException {
   Session s = (Session) session.get();
   // Ouvre une nouvelle Session, si ce Thread n'en a aucune
   if (s == null) {
   s = sessionFactory.openSession();
   session.set(s);
   }
   return s;
   }

 public static void closeSession()
      throws HibernateException {
   Session s = (Session) session.get();
   session.set(null);
   if (s != null)
   s.close();
   }
 }

This class is used in this abstract class by calling HibernateUtil.currentSession():

Code:

public abstract class AccesMetierBase {
   /*attributs*/
   public Session hibernateSession;
   
   /*contructeur*/
   public AccesMetierBase() {
      try {
         hibernateSession = HibernateUtil.currentSession();
      } catch (HibernateException e) {
         System.out.println("Hibernate : Erreur de recuperation de la session hibernate : " 
               + e.getMessages());
      }
   }
   
}

Problems:
I use this class in a struts project deployed on tomcat 5.0.28
When i deploye it at home (on windows XP pro, with j2ee sdk) there is no problems
But i got some problem when i deploye it at school.
When the HibernateUtil.currentSession() fonction is called, it's
impossible for it to find the hibernate.cfg.xml.

NB: For de deployement I only copy/paste the webapps folder of this website in the webapps folder of tomcat, and I started it.

Name and version of the database you are using:
pointbase installed whith j2ee 1.4

You might try to use a WAR file for deployment. Many modern IDEs will provide this export functionality. With a WAR file you can be sure that all necessary files are available at deployment and in a structure that the container can find.

ok,
but is there something to in the web.xml file or into another file in order the application find the confg file ?
