I have this code in the method main of my app:
Configuration cfg = new Configuration();
How can I catch the exceptions generated by this line?
The excpetion hasn't been catched by the try..catch block.
For example, I has put some different user and password, and the exception has not been catched.

I believe in Hibernate 3.x HibernateException now extends RuntimeException, so you'd want to catch (Throwable t) instead of catch (Exception e).

What is the code you have?

Code:
    public static void main(String[] args) {   
       Splash.getInstance().openSplash();
       try{
          GerenciadorPersistencia.criarFabricaSessoes();
       }catch(Throwable t){
          JOptionPane.showMessageDialog(null,"Erro ao criar fábrica de sessões",
                "Não foi possível criar fábrica de sessões. Talvez ocorreu um erro de conexão com o banco de dados.\n"+
                t.getCause()==null?t.getMessage():t.getMessage()+" "+t.getCause(),
                      JOptionPane.ERROR_MESSAGE);
       }


There is a looping printing these exception several times...until I stop the program. I changed the user name and password to force the exception, to test the code.

Code:

I forget to show you the code or GerenciadorPersistencia.criarFabricaSessoes

Code:
   public static void criarFabricaSessoes(){
      Configuration cfg = new Configuration();
      sessionFactory = cfg.configure().buildSessionFactory();
   }

And you are saying that your showMessageDialog never shows up?
