 Post subject: @Column(name="...") get's ignored with use of @IdClass

I'm really getting mad with this EJB3 stuff, because I'm trying to set up a concept for migrating EJB2.0-Entity-Beans to EJB3.0-Entities. Was testing it with OpenJPA - didn't work! Was testing it with EclipseLink - didn't work! And now I'm testing Hibernate and...

Ok, here is my problem. The log messages from the deployment show, that the annotation @Column(name="VTR_ID") at my pk-attribute vtrId gets ignored. I'm not positive, but I think it has to do with that I'm using an IdClass.

Has anyone a similar problem or - even better - a solution for how to map the attribute Vertrag.vtrId to the table-column EJB3_VTR.VTR_ID when using an Id-Class?!? Or am I doing anything wrong?!? (I really need the Id-Class in some other cases, that are more difficult. It won't help me to leave out the Id-Class-Annotation or to replace it by an embedded Id.)


Here is my entity:
Code:
import javax.persistence.*;
import de.ivv.aa.jif.business.TransferObject;

@Entity
@Table(name="EJB3_VTR")
@IdClass(VertragPK.class)
@NamedQueries({
    @NamedQuery(name="Vertrag.getMaxId", query="SELECT MAX(vtr.vtrId) FROM Vertrag AS vtr"),
    @NamedQuery(name="Vertrag.getMinId", query="SELECT MIN(vtr.vtrId) FROM Vertrag AS vtr")
})
public class Vertrag implements Serializable {   

    private Integer vtrId;
    private String vsnr;

    @Id @Column(name="VTR_ID")
    public Integer getVtrId() { return this.vtrId;}
    public void setVtrId(Integer aVtrId) { this.vtrId = aVtrId; }

    @Column(name="VSNR")
    public String getVsnr() { return this.vsnr; }
    public void setVsnr(String aVsnr) { this.vsnr = aVsnr; }
}

---------------------------------------------------------
import java.io.Serializable;

public class VertragPK implements Serializable {
   
    private Integer vtrId;
   
    public VertragPK(){}
    public VertragPK(Integer vtrId) { this.vtrId = vtrId; }
   
    public Integer getVtrId() { return this.vtrId; }
    public void setVtrId(Integer vtrId) { this.vtrId = vtrId; }
   
    public boolean equals(Object obj) {
        if (obj == this) { return true; }
        if (!(obj instanceof VertragPK)) { return false; }
        VertragPK pk = (VertragPK) obj;
        if ( pk.getVtrId().equals(this.vtrId)) { return true; }
        else { return false; }
    }
   
    public int hashCode() {
       //some custom implementation
    }
   
    public String toString() {
        //some custom implementation
    }

}


And this is the log-output from the deployment:
I marked the significant lines, that show which binding gets done.
