Hi! I really need help...
I'm using hibernate 2.1.2
 
I´m trying to insert o clob field into Oracle... I did the example located at page http://www.hibernate.org/56.html. What is wrong??? How can I insert o clob into Oracle?
The error that I have received for sizes bigger then 4000 caracteres is:

while ((line = reader.readLine()) != null)
{
sb.append(line);
}

System.out.println(sb.toString().length());

Teste teste = new Teste();
Configuration c = new Configuration();
c.configure(new File("hibernateTeste.cfg.xml"));
Session session = c.buildSessionFactory().openSession();
Transaction tx;

tx = session.beginTransaction();

teste.setId(new Long(11));
teste.setTexto(Hibernate.createClob(sb.toString()));

session.save(teste);
session.flush();
session.refresh(teste, LockMode.UPGRADE);

oracle.sql.CLOB clob = (oracle.sql.CLOB) teste.getTexto();

java.io.Writer pw = clob.getCharacterOutputStream();
pw.write(1);
pw.flush();
pw.close();
tx.commit();
session.close();

Thanks!
