hier ist mein Code für den Test:

public class BookEjbTest {

public static void initcontainer() throws Exception { 
    File module = new File("target/classes/cd/espoirmur/ejb");

    System.out.println("--------------ejb container sucessfully created----------" + Arrays.toString(module.listFiles()) + "---------liste des moduless"); 
    ctx = ec.getContext(); 
    System.out.println("--------------ejb context successfull sucessfully created----------"); 
} 

@AfterClass 
public static void closeContainer() throws Exception { 
    ec.close(); 
} 

@Test 
public void createBook() throws Exception { 
    Book book = new Book(); 
    long id = 12309; 
    book.setId(id); 
    book.setDescription("mon premier livre sur les EJB"); 
    book.setIllustrations(Short.MIN_VALUE); 
    book.setIsbn("ISBN-129-OK"); 
    book.setNbofpage(123); 
    book.setBookTitle("Debutez avec les EJB"); 
    book.setPrice(12.5); 
    System.out.println("-----------begin checking--------"); 
    InterfaceEjbLocal bookejb = (InterfaceEjbLocal) ctx.lookup("java:global/ejb/BookEjb");

     bookejb.enregistrer(book); 
     assertNotNull("ID should not be null", book.getId());

     assertNotNull(books); 
    } else { 
     System.out.println("-----------null object return--------"); 
    } 

}

}

der ejb-Code:

@Local(InterfaceEjbLocal.class) 
@Stateless 
public class BookEjb implements Serializable,InterfaceEjbLocal<Book>{ 
    @PersistenceContext(unitName = "BookStorePU") 
    private EntityManager em; 
    @Override 
    public List<Book> find() { 
     List<Book> Books = em.createNamedQuery("Book.findAll", Book.class).getResultList(); 
     return Books; 
    } 
    @Override 
    public Book findById(Long id) { 
     return em.find(Book.class, id); 
    } 
    @Override

     em.persist(entity); 
     return entity; 
    } 
    @Override

     em.remove(em.merge(entity)); 
    } 
    @Override 
    public Book update(Book entity) { 
     return em.merge(entity); 
    } 
    @Override 
    public String getReason() { 
     return "why je ne fonctionnne pas?????"; 
    } 
    public void setEm(EntityManager em) { 
     this.em = em; 
    } 
}

die lokale Schnittstelle:

package cd.espoirmur.Ejb; 

import java.util.List;

    public T findById(Long id); 

    public T enregistrer(T entity); 

    public void delete(T entity); 

    public T update(T entity); 

    public String getReason();

kann mir jemand helfen ??

ich denke, der Fehler ist in meinem EJB Lifecycle, wenn ich versuche, die persistance-Einheit zu injizieren, aber ich weiß nicht, wie es zu lösen, bekomme ich den gleichen Fehler rven, wenn ich nicht die lokale Schnittstelle implementieren .. Bitte hilf mir!!!!!

wenn BookEjb Serializable implementiert, sollte es haben private static final lange serialVersionUID = 1L; – Leo

Ist ' java: global/jdbc/BookStorePool' verweist auf eine Datenquelle oder einen JDBC-Pool? – ujulu

Es zeigt auf eine Datenquelle namens bookstorepool –

Ich könnte mich irren, aber es sieht so aus, als ob der Container die Persistenzeinheit nicht einrichten kann, weil Sie nicht alle herstellerspezifischen Eigenschaften der Eclipse-Persistenz angegeben haben Anbieter benötigt (insbesondere Verbindungsanmeldeinformationen).

gehen diese in den „Eigenschaften“ Abschnitt, und sind herstellerspezifisch (JBoss docs link), aber here's the example Eclipse-Link erhalten, und hier ist their docs zu diesem Thema. Also, ich würde das Hinzufügen dieser vorschlagen zu Ihrem persistance.xml (mit den entsprechenden Werten für die DB):

<properties> 
    <property name="javax.persistence.jdbc.driver" value="oracle.jdbc.OracleDriver"/> 
    <property name="javax.persistence.jdbc.url" value="jdbc:oracle:thin:@localhost:1521:orcl"/> 
    <property name="javax.persistence.jdbc.user" value="scott"/> 
    <property name="javax.persistence.jdbc.password" value="tiger"/> 
</properties>

Lassen Sie es mich versuchen. Ich gebe Ihnen die Rückmeldung. –

Diese Felder sind im Verbindungspool, der von der Datenquelle verwendet wird ... Sollte ich es nochmal spezifizieren? Ich füge es hinzu, aber nichts. –

Wenn Sie eine Datenquelle angeben, müssen Sie diese Eigenschaften nicht angeben. – ujulu
