Erro Hibernate

Assuntos Gerais Agile
#1

Alguem tem ideia do que seja, falta importar alguma coisas para o projeto??

[code]
SessionFactory sessionFactory = new Configuration().buildSessionFactory();

	Session session = sessionFactory.openSession();
	Transaction tx = session.beginTransaction();
	
	filiado.setBairro(jTextFieldBairro.getName());
	filiado.setCargo(jTextFieldCargo.getName());
	
	
	session.save(filiado);
	tx.commit();
	
	session.close();[/code]

Erro:

Pelo erro parece que falta o .jar do dom4j no classpath de sua aplicacao.
