Im new in hebirnate. Try execute example code.

public class HibernateUtil {

private static final SessionFactory sessionFactory;

static {
    try {
        // Create the SessionFactory
        sessionFactory = new Configuration().configure().buildSessionFactory();
    } catch (HibernateException ex) {
        throw new RuntimeException("Configuration problem: " + ex.getMessage(), ex);
    }
}

public static final ThreadLocal session = new ThreadLocal();

public static Session currentSession() throws HibernateException {
    Session s = (Session) session.get();
    // Open a new Session, if this Thread has none yet
    if (s == null) {
        s = sessionFactory.openSession();
        session.set(s);
    }
    return s;
}

public static void closeSession() throws HibernateException {
    Session s = (Session) session.get();
    session.set(null);
    if (s != null)
        s.close();
}
}


public class javism_jaxb_xml_to_object {
public static void main(String[] args) throws JAXBException
{
    Session session = HibernateUtil.currentSession();
  Transaction tx = null;
    tx = session.beginTransaction();
            javism_jaxb cust = new javism_jaxb();
            cust.setName("Vasay");
            cust.setId(1);
            cust.setAge(34);
            session.save(cust);
            tx.commit();

    You need to add apache commons logging jar in your classpath if you have it. Otherwise download it from apache and add it in your project and add it in project’s classpth.

    UPDATE

    download dom4j library here and add it in classpath.

    UPDATE2

    INFO: Hibernate 3.0.3 –> INFO LOG SHOWING hibernate version you are using.

    INFO: hibernate.properties not found –> INFO LOG SHOWING hibernate.properties not found. This is an alternate way to give hibernate properties, you do provide these properties in hibernate.cfg.xml.
