I have an issue with parent/child updation. I have a class User, which has an One to Many relation with another Class UserExtrnRel. I opulate values for the child in a set, that time the linking field User_id is not generated. while saving the value user_id is generated and updated in the parent table. but user_id is updated as null in the child table

public class User extends DefaultTableMapping implements UserI {

private Integer userId;
private String firstName;
private String lastName;
private String ntLogin;
private String email;
private Set profiles;
private boolean isBOUser;

private Integer boUserId;
private String boPassword;

private Boolean active;

private Set boUsers;


@Id
@Column(name = "USER_ID")
@GeneratedValue(generator="userInsSeq")
public Integer getUserId() {
return userId;
}

public void setUserId(Integer userId) {
this.userId = userId;
}

//,cascade = CascadeType.ALL .LAZY
@JoinColumn(name = "USER_ID" , insertable=false, updatable=false)
@OneToMany(cascade = CascadeType.ALL, targetEntity = UserExtrnRel.class, fetch = FetchType.EAGER )
@Cascade({org.hibernate.annotations.CascadeType.SAVE_UPDATE,
org.hibernate.annotations.CascadeType.DELETE_ORPHAN})
public Set getUserExtrnRel() {
return boUsers;
}

public void setUserExtrnRel(Set boUsers) {
this.boUsers = boUsers;
}
....
}
