===

I work with jee and JSF2.0 and hibernate 
 
I want to access my data in my xhtml page 
my data are stored in hashset in the managedBean

I don't find how to access this data in html

in java I use this : 

    public void SaveCommande(Commande c) {

        try {
            org.hibernate.Transaction tx = session.beginTransaction();
            session.save(c);
            Iterator it = c.getFichiers().iterator();
                while(it.hasNext())
                    session.save((Fichier)it.next());
            tx.commit();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
