Querying Postgresql using Hibernate (JPA) don't find table
===

I'm developing an application using JPA with Hibernate and Postgresql. Using Netbeans wizard, I created entity classes from the existing database. The extract from one of this classes is the following:

    @Entity
    @Table(name = "ADM_TYPES")
    @XmlRootElement
    @NamedQueries({
        @NamedQuery(name = "AdmTypes.findAll", query = "SELECT a FROM AdmTypes a"),
        @NamedQuery(name = "AdmTypes.findByCType", query = "SELECT a FROM AdmTypes a WHERE a.cType = :cType"),
        @NamedQuery(name = "AdmTypes.findByVlType", query = "SELECT a FROM AdmTypes a WHERE a.vlType = :vlType"),
        @NamedQuery(name = "AdmTypes.findByDsType", query = "SELECT a FROM AdmTypes a WHERE a.dsType = :dsType"),
        @NamedQuery(name = "AdmTypes.findByVlStatus", query = "SELECT a FROM AdmTypes a WHERE a.vlStatus = :vlStatus"),
        @NamedQuery(name = "AdmTypes.findByCTypePrefix", query = "SELECT a FROM AdmTypes a WHERE a.cType like :cTypePrefix")})
    public class AdmTypes implements Serializable {

In an EJB I have:

    @Stateless 
    @LocalBean
    public class ModelManagement {
        @PersistenceContext 
        private EntityManager em;
        
        public List<AdmTypes> listAdmTypesPrefix(String prefix){
            TypedQuery<AdmTypes> query = em.createNamedQuery("AdmTypes.findByCTypePrefix", AdmTypes.class);
            query.setParameter("cTypePrefix", "'%"+prefix+"%'");
            return query.getResultList();
        }

When I try to execute `ModelManagement.listAdmTypesPrefix("APREFIX")` It generates the following error:

I know that Postgres is kind of annoying with capitalized table names, but how can I change the query to point to "ADM_TYPES" instead of AdmTypes? Shouldn't this be done automatically (after all I created the entity class from the existing database)? What is wrong with the code?

Thanks!
