Ne peut pas ouvrir l'EntityManager pour l'opération au printemps

Je suis la construction d'une application de test avec JPA Hibernate 4.1.7 et le Printemps 3.1.3 sur le dessus.

Je suis un NPE à jta provoquant l'EntityManager à l'échec, ici, c'est la trace de la pile

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 11.134 sec <<< FAILURE!

J'ai googlé l'erreur à la mort et ne peut toujours pas trouver de solution.

Voici le test:

package cvut.dp.foodtables.service;
import static org.junit.Assert.*;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
public class FoodServiceImplTest extends BaseServiceTest
{
@Autowired
private FoodService foodService;
public FoodServiceImplTest()
{
super();
}
@Test
public void testSome()
{        
Long id = foodService.addFood("test", 15, "test");
assertEquals(1, foodService.getAllFood().size());
}
}

Qui s'étend

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
"classpath:/WEB-INF/context/applicationContext.xml"})
@TransactionConfiguration(defaultRollback=true, transactionManager="txManager")
@Transactional //extend the transactions to whole tests in order to rollback the tests
public class BaseServiceTest
{
public BaseServiceTest()
{
}
}

Je suppose que l'erreur à quelque part dans ma configuration, donc je ne vais pas poster toutes les sources ici...

Voici mon applicationContext.xml (edit: modification 3.1.xds fichiers, pas de changement)

Les plus googlé jusqu'réponse était que je devrait être la mise en veille prolongée.des transactions.jta.plate-forme de propriété dans persistance.xml, je n'en ai pas. C'est ma première application Java EE et vraiment, je ne sais pas exactement ce que je fais encore. Mais cette erreur est frustrant.
