[eclipselink-users] Error on deploy webapp

I am having troubles on deploy a very simple webapp on GFv3.1
using Eclipse Helios SR1 as IDE.
This is the exception I get,

cannot Deploy PruebaWEB

Deployment Error for module: PruebaWEB: Exception while loading the app : java.lang.Exception: java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: java.lang.NoClassDefFoundError: Lejb/CountryFacade;

This is the code in the ejb project,

public abstract class AbstractFacade<T> {

private Class<T> entityClass;

public AbstractFacade(Class<T> entityClass) {
this.entityClass = entityClass;

protected abstract EntityManager getEntityManager();

public void create(T entity) {

public void edit(T entity) {

public void remove(T entity) {

public T find(Object id) {
return getEntityManager().find(entityClass, id);

public List<T> findAll() {
javax.persistence.criteria.CriteriaQuery cq = getEntityManager().getCriteriaBuilder().createQuery();;
return getEntityManager().createQuery(cq).getResultList();

public List<T> findRange(int[] range) {
javax.persistence.criteria.CriteriaQuery cq = getEntityManager().getCriteriaBuilder().createQuery();;
javax.persistence.Query q = getEntityManager().createQuery(cq);
q.setMaxResults(range[1] - range[0]);
return q.getResultList();

public int count() {
javax.persistence.criteria.CriteriaQuery cq = getEntityManager().getCriteriaBuilder().createQuery();
javax.persistence.criteria.Root<T> rt = cq.from(entityClass);;
javax.persistence.Query q = getEntityManager().createQuery(cq);
return ((Long) q.getSingleResult()).intValue();

And the CountryFacade ejb looks,

public class CountryFacade extends AbstractFacade<Country> {

@PersistenceContext(unitName = "PruebaJPA")
private EntityManager em;

protected EntityManager getEntityManager() {
return em;

public CountryFacade() {

Both classes in a package named 'ejb'.

This happened to me with a JEE 5 MDB example developed to deploy on glassfish v2.x.
In the begining I tried on glassfish v3 and that exception was what I got. Later I deployed the app
on glassfish v2.x and it started to run correctly.

Where is it going wrong?

Thanks in advance,
