I'm trying to do a simple app with Hibernate. I've created hibernate.cfg.xml and mapping file Personne.hbm.xml. Once I start it I get an exception javax.naming.NoInitialContextException: Need to specify class name in environment or system property...
In detail: The error I am getting is this:

Since you said you are just starting to learn Hibernate, I think you have not intentionally tried to create a JNDI bound SessionFactory:
<session-factory
name="java:hibernate/SessionFactory">
I can see that this is a copy from the official Hibernate documentation. There the author explains that with this naming you are going to bind your SessionFactory to a JNDI context. And this is exactly what is not working for you because you have not configured that yet. The easiest solution for you is actually just to remove the name parameter and stop trying to do the binding.
