This should do it :

protected void buildConfiguration() {
    try {
        setCfg( new Configuration() );
        configure( cfg );
        if ( recreateSchema() ) {
            cfg.setProperty( org.hibernate.cfg.Environment.HBM2DDL_AUTO, "create-drop" );
        }
        for ( String aPackage : getAnnotatedPackages() ) {
            getCfg().addPackage( aPackage );
        }
        for ( Class<?> aClass : getAnnotatedClasses() ) {
            getCfg().addAnnotatedClass( aClass );
        }
        for ( String xmlFile : getXmlFiles() ) {
            InputStream is = Thread.currentThread().getContextClassLoader().getResourceAsStream( xmlFile );
            getCfg().addInputStream( is );
        }

        final ServiceRegistry serviceRegistry = new ServiceRegistryBuilder( cfg.getProperties() ).buildServiceRegistry();
        SessionFactoryImpl sessionFactoryImpl = (SessionFactoryImpl) getCfg().buildSessionFactory( serviceRegistry );
        ServiceRegistryImplementor serviceRegistryImplementor = sessionFactoryImpl.getServiceRegistry();
        EventListenerRegistry registry = serviceRegistryImplementor.getService( EventListenerRegistry.class );
        registerCustomListeners( registry );
        setSessions( sessionFactoryImpl );
    }
    catch ( HibernateException e ) {
        e.printStackTrace();
        throw e;
    }
    catch ( SearchException e ) {
        e.printStackTrace();
        throw e;
    }
    catch ( Exception e ) {
        e.printStackTrace();
        throw new RuntimeException( e );
    }
}
