UnknownServiceException: Unknown service requested (Hibernate/Spring) - spring

Question

This problem bothers me now for days ..
I'm trying to get the current session from my sessionFactor but receive an org.hibernate.service.UnknownServiceException: Unknown service requested exception.
I have no idea what causes this or what this exception does mean in particular. The exception gets thrown as getCurrentSession()gets called.
#Component
public class RestaurantOwnerRepository implements RestauranOwnerDAO {
private SessionFactory sessionFactory;
public RestaurantOwnerRepository(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
#Override
#Transactional
public List<Restaurant> getAvailableRestaurants(String sessionId) {
Session session = sessionFactory.getCurrentSession();
// ..
}
}
which I am calling in my servlet:
#Configurable
public class RestaurantInformationServiceImpl extends XsrfProtectedServiceServlet implements RestaurantInformationService {
private static final long serialVersionUID = -4088840947018614411L;
private final static Logger logger = Logger.getLogger(RestaurantInformationServiceImpl.class);
#Autowired
public RestauranOwnerDAO restaurantOwnerRepository;
#Override
public void init(ServletConfig config) throws ServletException {
super.init(config);
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("/appServlet/servlet-context.xml");
this.restaurantOwnerRepository = (RestauranOwnerDAO)applicationContext.getBean("restaurantOwnerRepository");
((ConfigurableApplicationContext)applicationContext).close();
}
#Override
public List<RestaurantDTO> getAvailableRestaurants() {
List<Restaurant> availableRestaurants = restaurantOwnerRepository.getAvailableRestaurants(getSessionId());
// ..
}
}
This is my servlet-context.xml file:
<?xml version="1.0" encoding="UTF-8"?>

I just don't have any idea how to solve that problem.
Any help on this would be appreciated!

So, I don't know why it came up to me to comment out the line
((ConfigurableApplicationContext)applicationContext).close();
in init(ServletConfig config) as such
#Override
public void init(ServletConfig config) throws ServletException {
super.init(config);
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("/appServlet/servlet-context.xml");
this.restaurantOwnerRepository = (RestauranOwnerDAO)applicationContext.getBean("restaurantOwnerRepository");
//((ConfigurableApplicationContext)applicationContext).close();
}
but not closing the application context sure did help here..
I didn't thought about this. I just followed the warning in Eclipse
Resource leak: 'applicationContext' is never closed
and closed it without thinking obviously..
