Pessoal, estou tentando fazer um projeto com JSF + Hibernate + Jboss, mas está dando erro ao iniciar o projeto. Estou seguindo explicações do livro “Programação Java para a Web”. Como sugestão do livro estou implementando a técnica Open Session in View, e pra isso estou utilizando uma classe Filter, mas por algum motivo que eu desconheço não está dando certo. O log dá o seguinte erro (não estou postando o log inteiro, apenas a parte do erro. Se for preciso eu posto o resto):

O erro diz que há uma dependência circular, mas eu não sei exatamente o que é isso. O meu mapeamento parece estar certo.
Classe Filter:
...
public class ConexaoHibernateFilter implements Filter {
private SessionFactory sessionFactory;
@Override
public void destroy() { }
@Override
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
try {
this.sessionFactory.getCurrentSession().beginTransaction();
chain.doFilter(request, response);
this.sessionFactory.getCurrentSession().getTransaction().commit();
this.sessionFactory.getCurrentSession().close();
} catch (Throwable e) {
try {
if (this.sessionFactory.getCurrentSession().getTransaction().isActive()) {
this.sessionFactory.getCurrentSession().getTransaction().rollback();
}
} catch (Throwable t) {
t.printStackTrace();
}
throw new ServletException(e);
}
}
@Override
public void init(FilterConfig config) throws ServletException {
this.sessionFactory = HibernateUtil.getSessionFactory();
}
}HibernateUtil:
...
public class HibernateUtil {
private static final SessionFactory SESSION_FACTORY = buildSessionFactory();
private static SessionFactory buildSessionFactory() {
try {
Configuration cfg = new Configuration();
cfg.configure("hibernate.cfg.xml");
return cfg.buildSessionFactory();
} catch (Throwable e) {
System.out.println("Criação inicial do objeto SessionFactory falhou. Erro: " + e);
throw new ExceptionInInitializerError(e);
