I try to do a very simple OneToMany association using JPA annotations, but it doesn't seem to work
in User:
Code:
@Entity
@Table(name = "USERS")
public class User implements Serializable {
private static final long serialVersionUID = 7125941441868989498L;
/** User's id in the corresponding table */
@Id
@GeneratedValue
@Column(name = "USER_ID")
private Long id = null;
@OneToMany(mappedBy="user")
Collection<Job> dispatchedJobs = new ArrayList<Job>();
in Job:
Code:
@Entity
@Table(name="JOBS")
public class Job implements Serializable{
@Id
@GeneratedValue
@Column(name="JOB_ID")
private Long id = null;
@ManyToOne
@JoinColumn(name = "USER_ID", nullable = false, updatable = false)
private User user;
}
and I get this:
Exception in thread "main" javax.persistence.PersistenceException: org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: model.User.dispatchedJobs[org.quartz.Job]
