Поиск языка EJB в классе POJO бросает NameNotFoundException

Я пытаюсь найти bean-объект в POJO, который находится в том же пакете, где находится компонент. Боб не имеет значения null, когда я использую его в моем классе контроллера @ManagedBean, и я могу выполнять операции CRUD. Вот код для поиска в ArticlesBundle.java:Поиск языка EJB в классе POJO бросает NameNotFoundException

public class ArticlesBundle extends ResourceBundle{     
protected static final String BASE_NAME = "ArticlesLcl.findForLocale"; 
private Map<String,String> messages = new HashMap<>();    
private Locale locale = FacesContext.getCurrentInstance().getViewRoot().getLocale(); 
protected final Control DB_CONTROL = new DBControl();  

public ArticlesBundle(){   
    setParent(ResourceBundle.getBundle(BASE_NAME, FacesContext.getCurrentInstance().getViewRoot().getLocale(), DB_CONTROL)); 
}   

protected ArticlesBundle(Locale locale){   
    setParent(ResourceBundle.getBundle(BASE_NAME, locale, DB_CONTROL));   
} 

public ArticlesBundle(Map<String,String> messages){ 
    this.messages = messages; 
}   

@Override 
protected Object handleGetObject(String key){   
    return messages != null ? messages.get(key) : parent.getObject(key); 
} 

@Override 
public Enumeration<String> getKeys(){   
    return parent.getKeys(); 
} 

protected class DBControl extends Control{ 
    @Override 
    public ResourceBundle newBundle 
      (String baseName, Locale locale, String format, ClassLoader loader, boolean reload) 
      throws IllegalAccessException, InstantiationException, IOException 
    {        
     String language = locale.getLanguage(); 
     Map<String,String> messages = getArticless(locale); 

     System.out.println("getArticles("+language+") = "+getArticles(locale)); 
     return new ArticlesBundle(messages); 
    }   
    public Map<String,String> getArticles(Locale locale){    
     String language = locale.getLanguage(); 
     try {    
      Context ctx = new InitialContext();    
      ArticlesLclFacade arBean = (ArticlesLclFacade) ctx.lookup("java:gesht/ArticlesLclFacade"); 
      List<ArticlesLcl> articles = arBean.getArticles(language); 
      for(Iterator<ArticlesLcl> it = articles.iterator(); it.hasNext();){ 
       ArticlesLcl article = it.next(); 
       messages.put(article.getArId().getArId().toString(), article.getArTitle());     
      }           

     } catch (NamingException ex) { 
      Logger.getLogger(test.class.getName()).log(Level.SEVERE, null, ex); 
     } 

     return messages; 
    }   
}   
}

В ArticlesFacade:

@Stateless 
public class ArticlesFacade extends AbstractFacade<ArticlesLcl> { 
@PersistenceContext(unitName = "gtestPU") 
private EntityManager em; 

@Override 
protected EntityManager getEntityManager() { 
    return em; 
} 

public ArticlesFacade() { 
    super(ArticlesLcl.class); 
} 
public List<ArticlesLcl> getArticless(String language){ 
    Query q = em.createNamedQuery("ArticlesLcl.findForLocale", ArticlesLcl.class); 
    q.setParameter("lang", language); 
    return q.getResultList(); 
} 
}

Грани-config.xml

<resource-bundle> 
     <base-name>com.gesht.bundles.ArticlesBundle</base-name> 
     <var>article</var> 
    </resource-bundle>

Это бросает следующее исключение:

Я использовал синтаксис ArticlesLclFacade arBean = (ArticlesLclFacade) ctx.lookup("java:global/gtest/ArticlesLclFacade"); и не более NamingException брошен.

@Stateless(mappedName="articlesLclFacade") 
public class ArticlesLclFacade extends AbstractFacade {

то в вашей статье Ьгу

ArticlesLclFacade arBean = (ArticlesLclFacade)ctx.lookup("articlesLclFacadee");

Или я думаю, вы также можете использовать EJB аннотацию, как это:

@EJB 
private ArticlesLclFacade arBean;

Я определил свой сеансовый компонент именно так, и в моем управляемом bean-компоненте я ввел его с помощью этой аннотации EJB таким образом. Но внутри этого POJO я должен искать свой bean-компонент, используя JNDI, и по какой-то причине я не знаю, что он всегда равен нулю. Возможности, насколько я могу предположить, мой метод POJO вызывается до того, как bean вводится или они живут в двух разных потоках. Для первого я попробовал метод инициализации '@ PostConstruct', который не работал, для второго я не знаю, что делать. – user2911374

Извините, что в моем ответе должно быть 'ArticlesLclFacade arBean = (ArticlesLclFacade) ctx.lookup (" articlesLclFacade ");' вместо 'ArticlesLclFacade arBean = (ArticlesLclFacade) ctx.lookup (" articlesLclFacadee ");' Можете ли вы опубликовать все кода, участвующего в этой части вашей программы? Я действительно хочу помочь вам в этом. –

Спасибо @Sujan, после того, как я создал POJO без основного метода, теперь я получаю 'javax.naming.NameNotFoundException: нет объекта, связанного с именем java: gtest/ArticleLclFacade', а не' Got null ComponentInvocation' – user2911374
