Create session factory in Hibernate 4

Question

I'm having trouble generating a session factory in Hibernate 4. In Hibernate 3 I simple did:

org.hibernate.cfg.Configuration conf= HibernateUtil     .getLimsInitializedConfiguration(systemConfiguration .getHibernateconfFile());  SessionFactory sf = conf.configure().buildSessionFactory(); 

Now I need to pass a ServiceRegistry class to buildSessionFactory, but the Javadocs are extremely vague on how to go about this. Any tips?

Yes, they have deprecated the previous buildSessionFactory API, and it's quite easy to do well.. you can do something like this..

EDIT : ServiceRegistryBuilder is deprecated. you must use StandardServiceRegistryBuilder

public void testConnection() throws Exception {              logger.info("Trying to create a test connection with the database.");             Configuration configuration = new Configuration();             configuration.configure("hibernate_sp.cfg.xml");             StandardServiceRegistryBuilder ssrb = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());             SessionFactory sessionFactory = configuration.buildSessionFactory(ssrb.build());             Session session = sessionFactory.openSession();             logger.info("Test connection with the database created successfuly.");     } 

For more reference and in depth detail, you can check the hibernate's official test case at https://github.com/hibernate/hibernate-orm/blob/master/hibernate-testing/src/main/java/org/hibernate/testing/junit4/BaseCoreFunctionalTestCase.java function (buildSessionFactory()).
