SessionFactory configuration problem

[toffolo]

Hey Marten, good morning!

Ok ... so I got the right difference from classes to entities since the beginning. Good news!

The fact is that my classes in 'muitobafao.model' are completely annotated (they are, in fact, entities). I pasted Comentario.java as an example class (as it is considerably -- 85% -- smaller than Usuario.java) so you can see how my classes are annotated. They all follow the same annotation style (I chose to annotate the fields).

Why do you say I shouldn't be using HibernateTemplate? The book says exactly the opposite... because when I use HibernateDaoSupport it simplifies my code (and as a side effect makes it more dependable upon Spring).
Would it be better for me to use SessionFactory directly and pass it as a constructor argument to my DAO classes?

If I got it right ... you are saying I should proceed the way taught by this tutorial. Is it?

Thanks again.

EDIT:

Well, I tried following that tutorial I posted above but when manually creating the SessionFactory (using the exact same piece of code provided in the website) the same exception happened:

I have already changed the libraries. And it didn't get fixed.
