[eclipselink-users] OneToMany unidirectional with composite PK
|
Please can you help me. I would like to have OneToMany unidirectional with composite PK.
Code:
public class UEmployee extends DataWithPropertyChange.Abstract implements Serializable, Cloneable {
@Id
@Column(name = "ID")
private int id;
@OneToMany(mappedBy = "employee", cascade = { CascadeType.MERGE/*, CascadeType.REMOVE*/, CascadeType.DETACH, CascadeType.PERSIST, CascadeType.REFRESH})
@OrderBy("dataType, azimuthDeg")
@PrivateOwned
private List<UData> dDataCollection;
}
// composite PK: dataType, azimuthDeg, employee
public class UData {
@Id
@Column(name = "DATA_TYPE", nullable = false)
private int dataType;
@Id
@Column(name = "AZIMUTH", precision = 4, scale = 0)
private float azimuthDeg;
@Id
@JoinColumn(name = "ID", referencedColumnName = "ID")
@ManyToOne
private UEmployee employee;
@Column(name = "DVALUE", precision = 4, scale = 0)
private float value;
}
I'm using latest release: Eclipselink 2.1.0.v20100614-r7608.
I can't use @JoinColumn because I get exception that I have to use @JoinColumns with all PK columns.
I would like to remove field 'UData.employee' and replace it with unidirectional mapping. Is it possible?
Thank you very much for help.
