EJB Entity not found?

Question

Hi,
It is weird that i am having this error event all my entities even i have listed all the entities in persistent config; i tested with the global option "include all Entity Classes.." too.
I am using glassfish 3.1.2 ; Netbeans 7.1 on XP.
have you got a clue for this?

If you have annotated your Entity classes correctly then you don't need to add entities to an xml file.
Look at the first line in the stack trace that references your code to see what code gave you that exception and post the line here.stack trace points to a function below:
     protected int countLike(String fieldName, String value) {
         CriteriaBuilder cb = getEntityManager().getCriteriaBuilder();
         javax.persistence.criteria.CriteriaQuery cq = cb.createQuery();
         javax.persistence.criteria.Root<T> rt = cq.from(entityClass);
        cq.select(getEntityManager().getCriteriaBuilder().count(rt));
        Expression ex = rt.get(fieldName);
        cq.where(cb.like(ex,"%"+ value+"%"));
        javax.persistence.Query q = getEntityManager().createQuery(cq);       
        return ((Long) q.getSingleResult()).intValue();
    }  the line it points to:
javax.persistence.criteria.Root<T> rt = cq.from(entityClass);and i assure the entity is annotated @Entity (it is auto generated from netbeans)
