I've created a simple example of a class with Hibernate, but I get the following errors:
Initial SessionFactory creation failed. java.lang.ExceptionInInitializerError java.lang.ExceptionInInitializerError at org.hibernate.cfg.Configuration.reset(Configuration.java:249) at org.hibernate.cfg.Configuration.<init>(Configuration.java:216) at org.hibernate.cfg.Configuration.<init>(Configuration.java:220) at it.univaq.mwt.tplabs0.Test.main(Test.java:14) Caused by: java.lang.NullPointerException at org.hibernate.util.ConfigHelper.getResourceAsStream(ConfigHelper.java:167) at org.hibernate.cfg.Environment.<clinit>(Environment.java:585) ... 4 more Exception in thread "main" java.lang.NullPointerException at it.univaq.mwt.tplabs0.Test.main(Test.java:20) My Test class:
package it.univaq.mwt.tplabs0; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; public class Test { public static void main(String[] args) { SessionFactory sessionFactory = null; try { sessionFactory = new Configuration().configure().buildSessionFactory(); } catch (Throwable ex) { System.err.println("Initial SessionFactory creation failed. " + ex); ex.printStackTrace(); } Session session = sessionFactory.getCurrentSession(); session.beginTransaction(); System.out.println("Creating element"); Element el = new Element("prova", 1); session.save(el); System.out.println("Committing Tx"); session.getTransaction().commit(); System.out.println("Closing Session"); if (session.isOpen()) session.close(); } } My Hibernate configuration file:

Launching this simple execution I get the error from above. The database I'm using is Oracle 11g.
What happened?
