Referencing EJB 3.0 ,problem

Question

Hello I have 2 session EJB 3.0 and I would reference one on body of another , but
I have an error form embedded OC4J when I run DEBUG .
Here is my simply code
TransactionController ---
package com.savino.banking.model.facade;
import com.savino.banking.model.entity.Transaction;
import com.savino.banking.model.entity.TransactionItem;
import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
@Stateless(name="TransactionController")
public class TransactionControllerBean implements TransactionController,
TransactionControllerLocal {
@PersistenceContext(unitName="Model")
private EntityManager em;
public TransactionControllerBean() {
public Object mergeEntity(Object entity) {
return em.merge(entity);
public Object persistEntity(Object entity) {
em.persist(entity);
return entity;
and I declare a reference to TransactionController into AdminController :
package com.savino.banking.model.facade;
import com.savino.banking.common.exception.BusinessException;
import com.savino.banking.model.entity.Cc;
import com.savino.banking.model.entity.CostCenter;
import com.savino.banking.model.entity.TypeTransaction;
import com.savino.banking.model.entity.UserCcLinks;
import com.savino.banking.model.entity.UserCcLinksPK;
import com.savino.banking.model.entity.Users;
import java.util.List;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
@Stateless(name="AdminController")
public class AdminControllerBean implements AdminController,
AdminControllerLocal {
@PersistenceContext(unitName="Model")
private EntityManager em;
@EJB(name="myController",beanInterface=TransactionControllerLocal.class,beanName="TransactionControllerLocal")
TransactionControllerLocal controller;
public AdminControllerBean() {
And this is the error that I caught :

AVVERTENZA: Impossibile risolvere il riferimento EJB "myController". La creazione di J2EEContext può tuttavia continuare.
