Comment valider le modèle de données avec JPA?

J'essaie d'obtenir JPA de validation pour le travail, mais il semble que la validation des annotations sont ignorés. J'ai trouvé cet exemple de JPA pour la validation de la SORTE: JPA Entité de Validation, mais il ne fonctionne pas pour moi. Le @NotNull et @Size annotations semblent être ignorés.

Comme dans la réponse mentionné ci-dessus je n'utilise que deux classes:

Customer.java:

package com.validation.test;

import javax.persistence.*;
import javax.validation.constraints.*;

@Entity
@Table(name = "T_CUSTOMER")
public class Customer {
    @Id
    @NotNull
    @SequenceGenerator(name = "customerIdSeq", sequenceName = "T_CUSTOMER_ID_SEQ", allocationSize = 1)
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "customerIdSeq")
    private Long id;

    @NotNull
    @Size(min = 3, max = 80)
    private String name;

    public Customer() {};

    public Customer(String name) {
        this.name = name;
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }    
}

CustomerTest.java:

package com.validation.test.test;
import static org.junit.Assert.*;
import javax.persistence.*;
import javax.validation.*;
import javax.validation.constraints.Size;
import org.junit.*;
import com.validation.test.Customer;
public class CustomerTest {
private static EntityManagerFactory emf;
private EntityManager em;
@BeforeClass
public static void createEntityManagerFactory() {
emf = Persistence.createEntityManagerFactory("testPU");
}
@AfterClass
public static void closeEntityManagerFactory() {
emf.close();
}
@Before
public void beginTransaction() {
em = emf.createEntityManager();
em.getTransaction().begin();
}
@After
public void rollbackTransaction() {
if (em.getTransaction().isActive()) {
em.getTransaction().rollback();
}
if (em.isOpen()) {
em.close();
}
}
@Test
public void nameTooShort() {
try {
Customer customer = new Customer("bo");
em.persist(customer);
em.flush();
fail("Expected ConstraintViolationException wasn't thrown.");
} catch (ConstraintViolationException e) {
assertEquals(1, e.getConstraintViolations().size());
ConstraintViolation<?> violation = e.getConstraintViolations().iterator().next();
assertEquals("name", violation.getPropertyPath().toString());
assertEquals(Size.class, violation.getConstraintDescriptor().getAnnotation().annotationType());
}
}
}

Le test échoue à la fail(...) si l'exception n'est jamais levée.

Comment puis-je faire (tout) un travail de validation avec JPA? Je ne peux pas utiliser Hibernate ou au Printemps.

Merci pour votre aide

EDIT: ajouté à hibernate validator pour pom.xml (sans effet)
