jboss apps need to save the session in 2 different databases

[gan.gary]

I have a jboss apps need to save the session in 2 different databases.
Does it mean i need to do something like this:

public MyClass() throws NamingException {
 InitialContext ctx = new InitialContext();
 //TODO : use "hibernate.cfg.xml" if tester
 SessionFactory sessionFactory = (SessionFactory)
 ctx.lookup("java:/hibernate/SessionFactory");
 //SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();

 session = sessionFactory.openSession();
 // session 2
 SessionFactory sessionFactory2 = (SessionFactory)
 ctx.lookup("java:/hibernate/SessionFactory2");


 session2 = sessionFactory2.openSession();
 }

// this go to db 1
Transaction tx = null;
try{
 tx = session.beginTransaction();
 Vector v = new Vector(hash1.keySet());
 Collections.sort(v);
 Long nUID = null;
 Iterator it = v.iterator();
 while (it.hasNext()) {
 nUID = (Long)it.next();
 Obj1 obj1= hash1.get(nUID);
 session.save(obj1);
}
 session.flush();

// this go to db 2
Transaction tx2 = null;
try{
 tx2 = session2.beginTransaction();
 Vector v = new Vector(hash2.keySet());
 Collections.sort(v);
 Long nUID = null;
 Iterator it = v.iterator();
 while (it.hasNext()) {
 nUID = (Long)it.next();
 Obj1 obj1= hash1.get(nUID);
 session2.save(obj1);
}
 session2.flush();

I have found other post quite similar http://www.jboss.com/index.html?module=bb&op=viewtopic&t=137065 with me?
