I went back to the beginning, and redid everything, and I have included all of the source for all the files. I have tried the suggestions, and I am at a loss, so any suggestions would be greatly appreciated.
All Java files:

		}catch(Throwable t){
			System.err.println("Initial SessionFactory creation failed " + t);
			throw new ExceptionInInitializerError(t);
		}
	}
	public static SessionFactory getSessionFactory() {
		return sessionFactory;
	}
}

	}

		UserVo u = null;

		Session session = HibernateUtil.getSessionFactory().getCurrentSession();

		//This should pull back UserId 4 First Name Test4 and emailId 2 with 
Test4@here.com
		u = (UserVo) session.createQuery("from UserVo where userId = ?").setInteger(0, 4).uniqueResult();
		session.getTransaction().commit();

		System.out.println(u.getEmail().getEmailAddress());
