my test class :

import dao.services; import dao.produit;  public class test {      public static void main(string[] args) {         // todo auto-generated method stub          services s = new services();         produit p = new produit("pc","sony vaio",(double )7500);         s.addproduit(p);      }  }

service.java :

package dao;  import org.hibernate.session; import util.hibernateutil; public class services {      public void addproduit(produit p){          session session = hibernateutil.getsessionfactory().getcurrentsession();         session.begintransaction();         session.save(p);         session.gettransaction().commit();      }  } 

and 2 classes objects ( produit , categorie ) , configuration files !

what think may source of error ?

thank :)

the dialect mysql myisam(if have) should be:

org.hibernate.dialect.mysqlmyisamdialect
