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) {
getEntityManager().persist(entity);
}
public void edit(T entity) {
getEntityManager().merge(entity);
}
public void remove(T entity) {
getEntityManager().remove(getEntityManager().merge(entity));
}
public T find(Object id) {
return getEntityManager().find(entityClass, id);
}
public List<T> findAll() {
javax.persistence.criteria.CriteriaQuery cq =
getEntityManager().getCriteriaBuilder().createQuery();
cq.select(cq.from(entityClass));
return getEntityManager().createQuery(cq).getResultList();
}
public List<T> findRange(int[]
range) {
javax.persistence.criteria.CriteriaQuery cq =
getEntityManager().getCriteriaBuilder().createQuery();
cq.select(cq.from(entityClass));
javax.persistence.Query q = getEntityManager().createQuery(cq);
q.setMaxResults(range[1] - range[0]);
q.setFirstResult(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);
cq.select(getEntityManager().getCriteriaBuilder().count(rt));
javax.persistence.Query q = getEntityManager().createQuery(cq);
return ((Long) q.getSingleResult()).intValue();
}
}
And the CountryFacade ejb looks,
@Stateless
public class CountryFacade extends AbstractFacade<Country> {
@PersistenceContext(unitName
= "PruebaJPA")
private EntityManager em;
protected
EntityManager getEntityManager() {
return em;
}
public CountryFacade() {
super(Country.class);
}
}
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,
Jose
