@OneToOne - Cascade all not saving the parent Id

guys ! I have problem with saving on the "child" table parent's id When persist the child object, the column with parent id is null..

Parent ( User class)

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "user")
public class User {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "user_id")
private long userId;

@Column(name = "name")
private String name;

@Column(name = "address")
private String address;

@Column(name = "postcode")
private int postCode;

Child (Credential class)

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.OneToOne;
import javax.persistence.Table;


@Entity
@Table(name="credential")
public class Credentials {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name="id")
private int id;

@Column(name="username")
private String username;

@Column(name="password")
private String password;


@OneToOne(cascade= CascadeType.ALL )
@JoinColumn(name="user_id")
public User user;

Application class

    User user = new User();

    user.setAddress("asdkapoda");
    user.setName("xaxaxaxa");
    user.setPostCode(3423);

    Credentials credit = new Credentials();
    credit.setPassword("sadsad");
    credit.setUsername("sdadsa");
    session.save(credit);

And in database Credential is with user_id = NULL. Hibernate 4.3

Hibernate is faithfully saving the fact that you, in fact, never associated the Credentials object with a User object. Try adding credit.setUser(user); before the save.
