[hibernate] non memorizza i dati nel DB

[Lucked]

ho fatto ill seguente programma:

class Test{

public static void main(String[] args){

CD cd = new CD("Piero", "Morgana", new Date(), 12.99);

try{

Configuration cfg = new Configuration().addClass(CD.class);
SessionFactory sessionFactory = cfg.buildSessionFactory();

Session session = sessionFactory.openSession();
session.save(cd);
session.flush();
session.close();

} catch (Exception e){}

}

}

l'errore è questo:

log4j:WARN No appenders could be found for logger (net.sf.hibernate.cfg.Environm
ent).
log4j:WARN Please initialize the log4j system properly.

che fare?

ho trovato nel codice di hibernate un log4j.properties e l'ho inserito nel mio codice sorgente. Mi da come risultato:

tutto questo che cosa potrebbe volermi dire? Alla luce che il record che volevo inserire non è memorizzato...
