I'm new to Hibernate. I have download the lastest version 4.1.2Final and i'm trying to connect to a Mysql Database.

Please find the sample of code not working :

try {
   Configuration configuration = new Configuration();
   serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();
   factory = configuration.buildSessionFactory(serviceRegistry);
   logger.info("Opening a session");
   Session session = factory.openSession();
   logger.info("Closing session");
   logger.info("Fin du programme principal");
catch (Throwable ex) {
   logger.error("Failed to create sessionFactory object." + ex);
   throw new ExceptionInInitializerError(ex);

Problem, i'm facing, is the following exception :

1297 [main] ERROR Inventory - Failed to create sessionFactory object.org.hibernate.HibernateException: Connection cannot be null when 'hibernate.dialect' not set
Exception in thread "main" java.lang.ExceptionInInitializerError
at Inventory.main(Inventory.java:31)

A while ago, i used the class HibernateUtil to get a Session but things have changed with hibernate 4.

Can anyone help me in solving the issue ?
