Hi all, I've decided to change hbm.xml style to annotations using hibernate. I had in my hbm.xml:

<hibernate-mapping package="by.sokol.jpr.data">
 <class name="Licence">
  <id name="licenceId">
   <generator class="native" />
  </id>
 <many-to-one name="user" lazy="false" cascade="save-update" column="usr"/>
 </class>
</hibernate-mapping>

And changed it to:

@Entity
public class Licence {

 @Id
 @GeneratedValue(strategy = GenerationType.AUTO)
 private int licenceId;

 @ManyToOne(targetEntity=User.class, fetch=FetchType.EAGER, cascade = CascadeType.ALL)
 @Cascade(value = { org.hibernate.annotations.CascadeType.SAVE_UPDATE })
 private User user;
}

And hibernate doesn't save user on saving. I really need help!
