java.lang.ClassCastException: gestcom.entities.Structure cannot be cast to gestcom.components.VopD
Bonjour, j'ai un petit souci au niveau de la cast.
je ramène des données d'une requête

private java.util.List<gestcom.components.VopD> VopDataList;
private javax.persistence.Query VopDataQuery;
VopDataQuery = java.beans.Beans.isDesignTime() ? null : gestcomPUEntityManager.createQuery("SELECT o.code,o.libelle,o.objet,o.montant,o.datefin,o.datedeb,o.datesais,o.statut,o.structure,o.nature,e.sens,sum(e.montant) from Operation o ,Ecriture e where o.code = e.operation and e.sens= 'C' group by o.code,o.libelle,o.objet,o.montant,o.datefin,o.datedeb,o.datesais,o.statut,o.structure,o.nature,e.sens");
VopDataList = java.beans.Beans.isDesignTime() ? java.util.Collections.emptyList() : structureQuery.getResultList(); |
Pour récupérer ses données de la requête j'ai crée une classe
