here is my code

public List<Dossier> getDossierFindAllParDepartementDBTECHandUrgen() {
    Calendar myFiveDaysAhead;
    myFiveDaysAhead = Calendar.getInstance();
    myFiveDaysAhead.add(Calendar.DATE, 5);

    TypedQuery<Dossier> query;
    query =
        em.createQuery("SELECT d FROM Dossier d WHERE d.depid=1 AND d.typeDossier = :tpd AND " +
                       "d.dateCreation < :fiveDaysAhead", Dossier.class);

    query.setParameter("tpd", "Urgent");
    query.setParameter("fiveDaysAhead", myFiveDaysAhead, TemporalType.TIMESTAMP);
    return getDossierFindAllParDepartementDBTECHandUrgen();
}
