Соответствующий шаблон является строгим, но для элемента 'tx: annotation-driven'

Я пытаюсь настроить JSF + Spring + hibernate, и я привязываюсь для запуска теста, но когда я использую этот "tx: annotation-driven" в моем файле application-context.xml, я получаю эту ошибку:

Соответствующий шаблон является строгим, но для элемента 'tx: annotation-driven' не найдено объявления

Вот мой application-context.xml:

и вот мой курс CourseServiceImplTest. Я еще не выполнил тесты:

public class CourseServiceImplTest {

    private static ClassPathXmlApplicationContext context;
    private static CourseService courseService;
    public CourseServiceImplTest() {
    }

    @BeforeClass
    public static void setUpClass() throws Exception {
        context=new ClassPathXmlApplicationContext("application-context.xml");
        courseService=(CourseService) context.getBean("courseService");
    }

    @AfterClass
    public static void tearDownClass() throws Exception {
        context.close();
    }

    @Before
    public void setUp() {
    }

    @After
    public void tearDown() {
    }

    /**
     * Test of getAllCourses method, of class CourseServiceImpl.
     */
    @Test
    public void testGetAllCourses() {
        System.out.println("getAllCourses");
        CourseServiceImpl instance = new CourseServiceImpl();
        List expResult = null;
        List result = instance.getAllCourses();
        assertEquals(expResult, result);
        // TODO review the generated test code and remove the default call to fail.
        fail("The test case is a prototype.");
    }

    /**
     * Test of getCourse method, of class CourseServiceImpl.
     */
    @Test
    public void testGetCourse() {
        System.out.println("getCourse");
        Integer id = null;
        CourseServiceImpl instance = new CourseServiceImpl();
        Course expResult = null;
        Course result = instance.getCourse(id);
        assertEquals(expResult, result);
        // TODO review the generated test code and remove the default call to fail.
        fail("The test case is a prototype.");
    }

и вот CourseServiceImpl:

@Service("courseService")
@Transactional
public class CourseServiceImpl implements CourseService{

    @Autowired
    private SessionFactory sessionFactory;
    @Override
    public List<Course> getAllCourses() {
        return sessionFactory.getCurrentSession().createQuery("from Course").list();    
    }

    @Override
    public Course getCourse(Integer id) {
        return (Course) sessionFactory.getCurrentSession().get(Course.class, id);
    }

    @Override
    public void save(Course course) {
       sessionFactory.getCurrentSession().saveOrUpdate(course);
    }

}
