The error I'm receiving is listed here.

That's my HibernateUtil.java

package com.rosejapan;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;;

public class HibernateUtil
{
    private static final SessionFactory sessionFactory;

    static
    {
        try
        {
            // Create the SessionFactory from hibernate.cfg.xml
            sessionFactory = new  AnnotationConfiguration().configure().buildSessionFactory();
        } catch(Throwable e)
        {
            System.err.println("Initial sessionFactory creation failed.  " + e);
            throw new ExceptionInInitializerError(e);
        }
    }

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

Everything looks all right... I've already included log4j-boot.jar in the CLASSPATH, but didn't resolved my problem.
