//--Service class--
@Service
public class myService implements myInterface {
    @Autowired
    private MyDao myDao;
    //some code
    myDao.updateMethod(/*some arguments*/);
    //some code   
}
//--Dao class--
@Repository
public class MyDao {
    @Transactional(transactionManager = sample_a)
    public void updateMethod(/*some arguments*/){
        newUpdateMethod(/*some arguments*/);
    }
    @Transactional(transactionManager = sample_a)
    public void newUpdateMethod(/*some arguments*/){
        /* Actual call to DB taking place */
    }
}
When I call updateMethod from service class it is giving transaction related exception- InvalidDataAccessApiUsageException - No transaction is currently active, Am I using @Transactional in right way? I also read somewhere @Transactional should not be used in class with @Repository annotation, but I have other methods with @Transactional in Dao class and they are working fine.
