@SuppressWarnings("unchecked")
public Boolean checarLogin(String login) {
session = HibernateUtil.getInstance();
Transaction tx = null;
try {
tx = session.beginTransaction();
String hql="from Usuario u where u.login= :login";
Query query = session.createQuery(hql);
List<Usuario> u = (List<Usuario>) query.setString("login", login).list();
Iterator iter = u.iterator();
if (!iter.hasNext())
{
System.out.println("login ja existe!");
return true;
}else
System.out.println("login disponivel!");
return false;
} catch (HibernateException e) {
tx.rollback();
} finally {
session.close();
}
return null;
}
public void validaLogin(ActionEvent e) {
IDaoUsuario idao = new DaoUsuario();
if(!idao.checarLogin(this.usuario.getLogin())){
mensagem("senhainvalida");
}
else{
if(idao.checarLogin(this.usuario.getLogin()))
mensagem("logininvalido");
}
}
