hi

im new and learning hib3.

I have 2 classes User and ContactDetails that have a one-to-one association.

User has a ContactDetails member.

I'm trying to save User and ContactDetails to the DB but only User is saved.

how do i get it to save contact details as well ?

User u = new User();
u.setAge(99);
u.setFirstname("bill");
u.setLastname("henry");
Contact c = new Contact();
c.setEmail("bob@world");
u.setContact(c);

HibernateUtil.getSessionFactory().getCurrentSession().save(u);

could you post the sourcecode of the two classes?

are you using JPA or xml mapping files?

here is the source, im using xml mapping files. Im not using any JPA



package events;

public class Contact {

private Long id;
String email;
User user;

public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}



}

</hibernate-mapping>

i found that one way to do it is change the line in the user xml file

to be like this:

<one-to-one name="contact" class="events.Contact" cascade="all"></one-to-one>

which will cascade all changes saves deletes etc
