Projeto EJB3 + JBoss 4.2, erro ao criar link entre os EJBs

Galera,
Implementei uma solução onde tenho um EAR com dois EJBs e um WAR.

Ambiente:
[list]JBoss 4.2.1.GA[/list]
[list]Netbeans 5.5.1[/list]

Estrutura:

  • Report.ear (Projeto EnterpriseApplication do NetBeans)
    = Report-Business-ejb (Projeto EJB Module do NetBeans)
    - ElementoGerenciadoFacade ( como @Stateless )
    Ob.: nesta classe eu tenho um @EJB private DAOFactory daoFactory;
    - ElementoGerenciadoFacadeLocal ( como @Local )
    = Report-DAO-ejb (Projeto EJB Module do NetBeans)
    - persistence.xml
    - iDAO
    - IElementoGerenciadoDAO
    - ElementoGerenciadoDAOImpl
    - DAOFactory ( como EJB @Stateless )

Código da DAOFactory (Um projeto EJB Module no Netbeans)

@Stateless
public class DAOFactory implements DAOFactoryLocal{
    
    /** Creates a new instance of DAOFactory */
    public DAOFactory() {
    }
    
    @PersistenceContext(unitName = "PU")
    private EntityManager entityManager;
    
    public ElementoGerenciadoDAOImpl getElementoGerenciadoDAO(){
        IDAO dao = new ElementoGerenciadoDAOImpl();
        dao.setEntityManager(entityManager);
        return (ElementoGerenciadoDAOImpl) dao;
    }
    
}

Código de ElementoGerenciadoFacade (Um outro projeto EJB Module no Netbeans)

@Stateless
public class ElementoGerenciadoFacade implements ElementoGerenciadoFacadeLocal {
    @EJB
    private DAOFactory daoFactory;    
    
    public ElementoGerenciadoFacade() {
    }    
    public List findAll() {
        ElementoGerenciadoDAOImpl dao = daoFactory.getElementoGerenciadoDAO();
        return dao.findAll(); 
        //em.createQuery("select object(o) from ElementoGerenciado as o").getResultList();
    }
    
}

Alguma idéia ?

Leandro,

Experimente acrescentar na anotação Stateless como está logo abaixo:

@Stateless(name="ElementoGerenciadoFacade", mappedName="ElementoGerenciadoFacade")
public class ElementoGerenciadoFacade implements ElementoGerenciadoFacadeLocal {
    @EJB
    private DAOFactory daoFactory;    
    
    public ElementoGerenciadoFacade() {
    }    
    public List findAll() {
        ElementoGerenciadoDAOImpl dao = daoFactory.getElementoGerenciadoDAO();
        return dao.findAll(); 
        //em.createQuery("select object(o) from ElementoGerenciado as o").getResultList();
    }
    
}

Faça o teste para ver se roda. O meu funciona deste modo com a diferença que eu implemento a interface remota também.

Para acessar pelo WAR eu uso um service locator:

public class ServiceLocatorBean implements IServiceLocator {
    ...
    ...
    private ElementoGerenciadoFacadeRemote _elementoGerenciadoFacade ;

    private Context ctx;

    public ServiceLocatorBean() {
        try {
            Hashtable env = new Hashtable();
            env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.enterprise.naming.SerialInitContextFactory");
            env.put(Context.PROVIDER_URL, "localhost");
            env.put(Context.URL_PKG_PREFIXES, "com.sun.enterprise.naming");
            this.ctx = new InitialContext(env);
            
            this._elementoGerenciadoFacade = (ElementoGerenciadoFacadeRemote)this.ctx.lookup("ElementoGerenciadoFacade");
        } catch (NamingException nex) {
            nex.printStackTrace();
        }
    }

    public ElementoGerenciadoFacadeRemote getElementoGerenciadoFacade() {
        return _elementoGerenciadoFacade;
    }
    ...
    ...
    ...
}

Cleiton,

Muito obrigado pela resposta.
Fui na fonte para resolver este problema, mas ainda tenho um erro ao executar a consulta.

Link para o Post: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=122964

Resumindo o que eu tinha que fazer para injetar o DAO era injetar a Interface Local em vez da classe de implementação.

Exemplo:

@EJB  
private DAOFactoryLocal daoFactory;

Mas, a exceção que continua dando ao executar a consulta:

Galera,
O problema era o maldito NetBeans que tava dando problema, pois eu tava iniciando a Aplicação pelo Debug-mode e isso não funciona no NetBeans.(Eu tenho que Atachar um Debugger se eu quiser debugar)
Eu queria disponibilizar um Tutorial para todos de como criar aplicações JEE (Modularizadas) no NetBeans.
