Hi!
I'm new to Hibernate and am having a problem I cannot seem to get past. I've been struggling with this for a couple days, and I'm out of options. I know I'm missing something very obvious, and very noobish, but I've had no luck. I've even read the Annotations manual cover to cover.
So here goes. I have a very simple setup:
Code:
@Entity
public class User implements Serializable {
private static final long serialVersionUID = 1L;
private String _username;
private long _id;
private Set<Campaign> _campaigns = new HashSet<Campaign>();
@Id @GeneratedValue(strategy = GenerationType.AUTO)
public long getId() { return _id; }
public void setId(long id) { _id = id; }
@Column(nullable = false, unique = true, length = 32)
public String getUsername() { return _username; }
public void setUsername(String username) { _username = username; }
@OneToMany (mappedBy="user")
public Set<Campaign> getCampaigns() { return _campaigns; }
public void setCampaigns(Set<Campaign> campaigns) { _campaigns = campaigns; }
}
@Entity
public class Campaign implements Serializable {
private static final long serialVersionUID = 1L;
private String _name;
private User _user;
private long _id;
@Id @GeneratedValue(strategy=GenerationType.AUTO)
public long getId() { return _id; }
public void setId (long id) { _id = id; }
@Column(nullable = false, unique = false )
public String getName() { return _name; }
public void setName (String name) { _name = name; }
@ManyToOne( cascade = {CascadeType.PERSIST, CascadeType.MERGE} )
@JoinColumn (name="user_fk")
public User getUser() { return _user; }
public void setUser (User user) { _user = user; }
}
When my webapp starts, I get the following error message in my logs:
FATAL - org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: com.wygand.dnd.User.campaigns[com.wygand.dnd.Campaign]
I've tried various annotations, but nothing works.
Hibernate version: 3.2
Mapping documents: in hibernate.cfg.xml I have:
<!-- Persistent classes -->
<mapping class="com.wygand.dnd.Campaign"/>
<mapping class="com.wygand.dnd.User"/>
Code between sessionFactory.openSession() and session.close():
// Just to test
List users = HibernateUtil.getSession().createCriteria(User.class).list();
List campaigns = HibernateUtil.getSession().createCriteria(Campaign.class).list();
