Hibernate – Unable to load class [oracle.jdbc.driver.Oracle Driver]

I am working on an application involving hibernate.
I am getting this exception when I invoke my application:

This is the hibernate.cfg.xml:

This is Hibernate Utility file:

public class HibernateUtility 
{

    private static final String CONFIGURATION_LOCATION = "com/infy/EPP/resources/hibernate.cfg.xml";
    private static SessionFactory sessionFactory = null;
    private static ServiceRegistry serviceRegistry;

    public synchronized static SessionFactory createSessionFactory() {
        if (sessionFactory == null) 
        {
            try {
                // Step1 : Loading the configuration details from
                // hibernate.cfg.xml
                Configuration configuration = new Configuration()
                        .configure(CONFIGURATION_LOCATION);
System.out.println("configuration in Utility=="+configuration); //---//syso1

                // Step2 : Creating ServiceRegistry using the
                // StandardServiceRegistryBuilder and Configuration defined in
                // Step 1

                serviceRegistry = new StandardServiceRegistryBuilder()
                        .applySettings(configuration.getProperties()).build();
                System.out.println("serviceRegistry=="+serviceRegistry); ---//syso 2

                // Step3 : Creating the SessionFactory using the Configuration
                // and serviceRegistry.

                sessionFactory = configuration
                        .buildSessionFactory(serviceRegistry);
                System.out.println("sessionFactory==="+sessionFactory);   ---//syso 3


            } 
            catch (Exception e) 
            {
            e.printStackTrace();
                EppLogger.logError("HibernateUtility",
                        "createSessionFactory", e.getMessage());
            }
        }

        return sessionFactory;
    }

}

This is the DAO class method where I invoke it:

public Login authorize(Login to) throws Exception 
    {
        LoginEntity le = null;
    SessionFactory sessionFactory = null;
        Session session = null;
        Login login =null;
        try {
            sessionFactory = HibernateUtility.createSessionFactory();
            session=sessionFactory.openSession();
            session.beginTransaction();
            le = (LoginEntity)session.get(LoginEntity.class, to.getUserId());
            if (le != null) 
            {
                 login = new Login();
                login.setPassword(le.getPassword());
                login.setRole(le.getRole());
                login.setStatus(le.getStatus());
                login.setUserId(le.getUserId());
            }
            session.getTransaction().commit();
            }
        catch (PersistenceException exception) {
            EppLogger.logError(this.getClass().getName(), "authorize",
                    exception.getMessage());
            throw new Exception("DAO.TECHNICAL_ERROR");
        }
        catch (Exception e) 
        {
            e.printStackTrace();
            EppLogger.logError(this.getClass().getName(), "authorize", e.getMessage());
            throw new Exception("DAO.TECHNICAL_ERROR");
        } 
        finally 
        {
            if(session!=null)
            {
            session.close();
            sessionFactory.close();
            }
        }
        return login;
    }

I have ojdbc7 under lib folder. Still it is not working.
I have gone through several pages on SO which suggest to add ojdbc14 in classpath. Still didn't work out

UPDATE:
I have put some syso statements in Hibernate Utility file. I am getting value of first 2 but not the 3rd syso.
