I am getting this error when I run my project and can't figure what's going on.

This is my InicioBean class

package com.sepa.controller;

import com.sepa.model.Provincia;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;

import java.util.List;

import com.sepa.util.HibernateUtil;

import org.hibernate.Session;
import org.hibernate.Query;

@ManagedBean(name = "inicioBean", eager = true)
@RequestScoped
public class InicioBean {

    private Provincia provincia;
    List<Provincia> provincias;
    String algo;

    public List<Provincia> getProvincias() {
        Session session = null;
        provincias = null;
        try {
            session = HibernateUtil.getSessionFactory().openSession();
            Query query = session.createQuery("from Provincia");
            provincias = (List<Provincia>) query.list();
        } catch (Exception e) {
            System.out.println(e.getMessage());
        } finally {
            if (session != null) {
                session.close();
            }
        }
        return provincias;
    }
}

This is my HibernateUtil class

package com.sepa.util;

import org.hibernate.cfg.Configuration;
import org.hibernate.SessionFactory;

public class HibernateUtil {

    private static final SessionFactory sessionFactory;

    static {
        try {
            // Create the SessionFactory from standard (hibernate.cfg.xml)
            // config file.
            sessionFactory = new Configuration().configure().buildSessionFactory();
        } catch (Throwable ex) {
            // Log the exception.
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}

This is my hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/SEPA</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">sepaweb</property>
        <mapping class="com.sepa.model.Provincia"/>
    </session-factory>
</hibernate-configuration>

I really don't know what's going on, I tried a lot of things, changed hibernate.cfg.xml's folder, tryed many HibernateUtil files but I can't get this work.

Project's structure

Thank!

Where is this class com.sepa.util.NewHibernateUtil? – RubioRic
can you provide your full stack trace of exception? – subbu royal
@RubioRic I copied it wrong , that was one of many attempts. – Gonzalo Fernandez
It seems that you're not deploying your project correctly. Your stack trace can be summarized as: Server can not found com.sepa.util.HibernateUtil class. – RubioRic
@RubioRic I know, but I tryed copying HibernateUtil class in all folders and didnt work so I am very confused. – Gonzalo Fernandez

Solved the problem. The HibernateUtil isn't correct. Changed for: 

import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.SessionFactoryBuilder;
import org.hibernate.boot.Metadata;
import org.hibernate.boot.MetadataSources;

public class HibernateUtil {
    private static SessionFactory sessionFactory;

    private static SessionFactory buildSessionFactory() {
        StandardServiceRegistry standardRegistry = new StandardServiceRegistryBuilder().
                configure("hibernate.cfg.xml").build();

        Metadata metadata = new MetadataSources(standardRegistry).getMetadataBuilder().
                build();

        SessionFactoryBuilder sessionFactoryBuilder = metadata.getSessionFactoryBuilder();

        SessionFactory sessionFactory = sessionFactoryBuilder.build();

        return sessionFactory;
    }

    public static SessionFactory getSessionFactory() {
        if (sessionFactory == null) {
            sessionFactory = buildSessionFactory();
        }
        return sessionFactory;
    }
}

And if you're using glassfish will need paste jboss-logging-3.3.0.Final.jar in glassfish4\glassfish\modules. (Rename to jboss-logging and replace the other)
