En passant par deux paramètres à une requête nommée

J'ai le texte suivant namedquery sur mon entité "Intervention ":

 @NamedQuery(name = "Intervention.findNextMission", query = " SELECT i FROM Intervention  i       WHERE i.heureDebut> :DateToBeSpecified and i.idAgent= :idAgent")`

je ne sais pas comment appeler cette requête dans mon code par le passage de deux paramètres : la date,l'id. Normalement, il devrait être comme ceci :

List <Intervention> ListOfInterventions = em.createNamedQuery("Intervention.findNextMission").setParameter().getResultList();

quoi mettre entre les parenthèses de setParameter() ??

voici le code de mon entité d'Intervention :

    @Entity
@Table(name = "intervention")
@XmlRootElement
@NamedQueries({
@NamedQuery(name = "Intervention.findAll", query = "SELECT i FROM Intervention i"),
@NamedQuery(name = "Intervention.findByIdIntervention", query = "SELECT i FROM Intervention i WHERE i.idIntervention = :idIntervention"),
@NamedQuery(name = "Intervention.findByHeureDebut", query = "SELECT i FROM Intervention i WHERE i.heureDebut = :heureDebut"),
@NamedQuery(name = "Intervention.findByHeureFin", query = "SELECT i FROM Intervention i WHERE i.heureFin = :heureFin"),
@NamedQuery(name = "Intervention.findNextMission", query = " SELECT i FROM Intervention i WHERE i.heureDebut> :DateToBeSpecified and i.idAgent= :idAgent")})
