[HIBERNATE] Conf et classe not found
Bonjour,
Voila je débute avec hibernate et j'ai le soucis suivant :
j'utilise une doc d'hibernate et j'en suis à mon premier essaie, j'ai fait les fichiers de conf et le mapping et lorsque je lance mon test java me dit qu'il ne trouve pas mon POJO, voici mon exemple :

| package events;
import java.util.Date;
public class Event {
private long id;
private String title;
private Date date;
/**
* @return Returns the date.
*/
public Date getDate() {
return date;
}
/**
* @param date The date to set.
*/
public void setDate(Date date) {
this.date = date;
}
/**
* @return Returns the id.
*/
public long getId() {
return id;
}
/**
* @param id The id to set.
*/
public void setId(long id) {
this.id = id;
}
/**
* @return Returns the title.
*/
public String getTitle() {
return title;
}
/**
* @param title The title to set.
*/
public void setTitle(String title) {
this.title = title;
}
