I did the following program:

Quote:
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){}

}

}


the error is this:

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


I found a log4j.properties in the hibernate code and I put in my source code. the result is:
