Foreign key in a composite primary key

[jonathan12]

Hello,

I use an entity "Commentaire" with a composite primary key and in this key, I have a foreign key on another entity (Journal).

@NamedQueries( {
 @NamedQuery(name="commentaire.findAll",
 query="FROM Commentaire"),
 @NamedQuery(name="commentaire.findByActivite",
 query= "FROM Commentaire " +
 "WHERE actif = :activite"),
 @NamedQuery(name="commentaire.findByDate",
 query= "FROM Commentaire " +
 "WHERE date = :date"),
 @NamedQuery(name="commentaire.findByGestionnaire",
 query= "FROM Commentaire " +
 "WHERE gestionnaire = :gestionnaire"),
 @NamedQuery(name="commentaire.findByMouvement",
 query= "FROM Commentaire " +
 "WHERE annee = :annee AND journal.idJournal = :idJournal AND chrono = :chrono")

})
@Entity
@IdClass(CommentairePk.class)
@Table(name="SCHEMA.COMMENTAIRE")
public class Commentaire implements Serializable {
 private static final long serialVersionUID = -2679761258372320963L;

 private String annee;
 private Journal journal;
 private int chrono;
 private String gestionnaire;
 private Date date;
 private String commentaire;
 private Boolean actif;
 private SysInfo sysInfo;

 @Id
 public String getAnnee() {
 return annee;
 }
 public void setAnnee(String annee) {
 this.annee = annee;
 }

 @ManyToOne(cascade={CascadeType.ALL})
 @JoinColumn(name="IDJOURNAL")
 @Id
 public Journal getJournal() {
 return journal;
 }
 public void setJournal(Journal journal) {
 this.journal = journal;
 }

 @Id
 public int getChrono() {
 return chrono;
 }
 public void setChrono(int chrono) {
 this.chrono = chrono;
 }

 @Id
 public String getGestionnaire() {
 return gestionnaire;
 }
 public void setGestionnaire(String gestionnaire) {
 this.gestionnaire = gestionnaire;
 }

 @Id
 public Date getDate() {
 return date;
 }
 public void setDate(Date date) {
 this.date = date;
 }

....
}

But when I launch my test on this entity, I have this exception :

org.hibernate.QueryException: could not resolve property: idJournal

When I remove journal from the primary key, it's all right.

Someone has a solution ?

Thank you
