Unresolved <ejb-link>

Question

I'm developing in NetBeans 7, with EJB3.1 and Glassfish 3.1. I am trying to reference the Local Interface of a Session Bean in a JAR from a POJO in a WAR. When I deploy to Glassfish I receive:

SEVERE: Unresolved <ejb-link>: TaskTool-ejb#ContextFacade
SEVERE: Exception while deploying the app [com.oracle.eas_TaskTool-ear_ear_1.0-SNAPSHOT]
SEVERE: Error: Unresolved <ejb-link>: TaskTool-ejb#ContextFacade

I used the NetBeans helper to generate the code to reference the Session Bean's Local Interface and it generated the <ejb-local-ref> section in web.xml for me.

@Local
public interface ContextFacadeLocal {
    void create(Context context);
    void edit(Context context);
    void remove(Context context);
    Context find(Object id);
    List<Context> findAll();
    List<Context> findRange(int[] range);
    int count();
    List<Context> findRootContexts();
}

@Stateless
public class ContextFacade extends AbstractFacade<Context> implements ContextFacadeLocal {
    @PersistenceContext(unitName = "TaskToolPU")
    private EntityManager em;

    protected EntityManager getEntityManager() {
        return em;
    }

    public ContextFacade() {
        super(Context.class);
    }

    @Override
    public List<Context> findRootContexts() {
        CriteriaBuilder builder = em.getCriteriaBuilder();
        CriteriaQuery<Context> query = builder.createQuery(Context.class);
        Root<Context> c = query.from(Context.class);
        query.select(c).where(builder.isNull(c.get("parent")));
        query.orderBy(builder.asc(c.get("id")));

        TypedQuery<Context> q = em.createQuery(query);
        return q.getResultList();
    }
}

@FacesConverter(value = "contextConverter")
public class contextConverter implements Converter {

    ContextFacadeLocal contextFacade = lookupContextFacadeLocal();

    @Override
    public Object getAsObject(FacesContext fc, UIComponent uic, String string) {
        return contextFacade.find(string);
    }

    @Override
    public String getAsString(FacesContext fc, UIComponent uic, Object o) {ntityManager() {
        return em;
    }

    public ContextFacade() {
        super(Context.class);
    }

    @Override
    public List<Context> findRootContexts() {
        CriteriaBuilder builder = em.getCriteriaBuilder();
        CriteriaQuery<Context> query = builder.createQuery(Context.class);
        Root<Context> c = query.from(Context.class);
        query.select(c).where(builder.isNull(c.get("parent")));
        query.orderBy(builder.asc(c.get("id")));

        TypedQuery<Context> q = em.createQuery(query);
        return q.getResultList();
    }
}

@FacesConverter(value = "contextConverter")
public class contextConverter implements Converter {

    ContextFacadeLocal contextFacade = lookupContextFacadeLocal();

    @Override
    public Object getAsObject(FacesContext fc, UIComponent uic, String string) {
        return contextFacade.find(string);
    }

    @Override
    public String getAsString(FacesContext fc, UIComponent uic, Object o) {
        return ((Context) o).getId().toString();
    }

    private ContextFacadeLocal lookupContextFacadeLocal() {
        try {
            javax.naming.Context c = new InitialContext();
            //return (ContextFacadeLocal) c.lookup("java:global/com.oracle.eas_TaskTool-ear_ear_1.0-SNAPSHOT/com.oracle.eas_TaskTool-ejb_ejb_1.0-SNAPSHOT/ContextFacade!com.oracle.eas.ejbs.ContextFacadeLocal");
            return (ContextFacadeLocal) c.lookup("java:comp/env/TaskTool-ejb#ContextFacade");

        } catch (NamingException ne) {
            Logger.getLogger(getClass().getName()).log(Level.SEVERE, "exception caught", ne);
            throw new RuntimeException(ne);
        }
    }
}

        <ejb-link>TaskTool-ejb#ContextFacade</ejb-link>
    </ejb-local-ref>
</web-app>

UPDATE

For clarity:

I don't have an ejb-jar.xml at all.

Using either <ejb-link>TaskTool-ejb/ContextFacade</ejb-link> or <ejb-link>com.oracle.eas_TaskTool-ejb_ejb_1.0-SNAPSHOT/ContextFacade</ejb-link> works.

Please see bkail answers below for explanation. Many thanks!

Answer 1

I had the same issue when trying to deploy my application, NetBeans generated this code in my web.xml on its own.

Check your web.xml and see if you see this:

<ejb-local-ref>
        <ejb-ref-name>appName</ejb-ref-name>
        <ejb-ref-type>Session</ejb-ref-type>
        <ejb-link>AppName#SomeClass</ejb-link>
    </ejb-local-ref>

if so just remove it comepletely, it should deploy after.
