when i ran the project without including the hibernate configuration and mapping files , the project works correctly
but if i added these files using the "hibernate synchronizer" a problem will be shown
please i really need your help
by the way i work with :
eclipse juno ,
tomcat as server ,
jsf2 (primefaces) ,
hibernate 4
and the database :
postgreSQL
javax.servlet.ServletException: org/hibernate/HibernateException
javax.faces.webapp.FacesServlet.service(FacesServlet.java:606)
