Hello,

I´m having troubles to start working with Hibernate Annotations. The thing is that when I try to access to the SessionFactory for the first time in my application, it fails throwing an Exception.

It´s very strange because I have a standalone class in my project that also call to HibernateUtil class to create the SessionFactory, but when this class do the job, it seems to work properly. In the other hand, when I deploy my application with ant and try to access SessionFactory, it fails like I said before.

Finally, I didn´t know if this was the correct thread to publish my message or not. If I am wrong, please excuse me, and if an admin could move it to the good place I will be very pleased.

Hibernate version:
Hibernate 3.2.5
Hibernate Annotations 3.3.0.GA

Mapping documents:

@Entity
@Table(name = "NEWS")
public class New {

/**
* Clave primaria de la noticia.
*/
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;

/**
* Título de la noticia.
*/
@Column(nullable = false, length = 50)
private String title;

/**
* Descripción de la noticia.
*/
@Column(nullable = false)
@Lob
private String description;

/**
* Fecha de expiración de la noticia, a partir de la cual no tendrá cabida
* en el gestor.
*/
@Column(nullable = false)
@Temporal(value = TemporalType.TIMESTAMP)
private Calendar expirationDate;

/**
* Usuario autor de la noticia.
*/
@ManyToOne
@JoinColumn(name = "USER_FK", nullable = false)
private User author;

__________________________________________________

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

/**
* Clave primaria del usuario.
*/
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;

/**
* Nombre del usuario.
*/
@Column(nullable = false, length = 30)
private String name;

/**
* Apellidos del usuario.
*/
@Column(nullable = false, length = 50)
private String surname;

/**
* Login, nombre identificativo y único del usuario en el sistema.
*/
@Column(nullable = false, length = 15, unique = true)
private String login;

/**
* Contraseña de acceso del usuario.
*/
@Column(nullable = false, length = 10)
private String password;

/**
* Colección de noticias de un usuario.
*/
@OneToMany(mappedBy = "author", cascade = { CascadeType.ALL })
@org.hibernate.annotations.Cascade(value = org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
private Set<New> news = new HashSet<New>();

In HibernateUtil I do this:

static {
try {
sessionFactory = new AnnotationConfiguration().buildSessionFactory();//it fails here

} catch (Throwable ex) {
logger.warn(ex);
throw new ExceptionInInitializerError(ex);
}
}
