java.lang.NoClassDefFoundError: Could not initialize class xxx.xxx.xxx.HibernateUtil

Question

Herewith I added my source code of web.xml

Answer 1

According codejava.net the HibernateUtil for hibernate-core-4.x looks like this:

...
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;

public class HibernateUtil {
    private static SessionFactory sessionFactory;

    public static SessionFactory getSessionFactory() {
        if (sessionFactory == null) {
            // loads configuration and mappings
            Configuration configuration = new Configuration().configure();
            ServiceRegistry serviceRegistry
                = new StandardServiceRegistryBuilder()
                    .applySettings(configuration.getProperties()).build();

            // builds a session factory from the service registry
            sessionFactory = configuration.buildSessionFactory(serviceRegistry);           
        }

        return sessionFactory;
    }
}
....

It is slightly optically different than example above, but the effect is the same. It is needed, to ensure, that old dictionary hibernate-3.x is really not present.
