Hello I am creating an entity user which hold an compound primairy key. consisting of id and department_id. The department_id is set by the code but the id should be generated by the Table Generator. BUt this value stay -1.

Can any one point me where it could go wrong.

At the moment i have:


@Entity
@IdClass(UserEntityPk.class)
@Table(name = "KIEKEBOE_USERS")
public class UserEntity implements java.io.Serializable {

  @TableGenerator(name = "userIdGen", table = "KIEKEBOE_SEQUENCE_GENERATOR", pkColumnName = "GEN_KEY", valueColumnName = "GEN_VALUE", pkColumnValue = "USER_ID", initialValue = 203, allocationSize = 1)
  @Id
  @GeneratedValue(strategy = GenerationType.TABLE, generator = "userIdGen")
  @Column(name = "USER_ID", nullable = false)
  private int id = -1;

  @Id
  @Column(name = "DEP_ID", nullable = false)
  private int depId = -1;


  public int getId() {
     return id;
  }
  public int getDepId() {
    return depId;
  }

The Pk class is:

@Embeddable
public class UserEntityPk implements Serializable {


  private int id = -1;

  private int depId = -1;

  public UserEntityPk() {
    super();
  }

  @Id
  @Column(name = "DEP_ID", nullable = false)
  public int getDepId() {
    return depId;
  }

  @TableGenerator(name = "userIdGen", table = "KIEKEBOE_SEQUENCE_GENERATOR", pkColumnName = "GEN_KEY", valueColumnName = "GEN_VALUE", pkColumnValue = "USER_ID", initialValue = 203, allocationSize = 1)
  @Id
  @GeneratedValue(strategy = GenerationType.TABLE, generator = "userIdGen")
  @Column(name = "USER_ID", nullable = false)
  public int getId() {
    return id;
  }

  public void setDepId(int newDepId) {
    depId = newDepId;
  }

  public void setId(int newId) {
    id = newId;
  }

}
