What is the role of HibernateUtil?

Question

I'm new to Hibernate, and everytime I come across a Hibernate tutorial there is a mention of HibernateUtil class ?

What actually does it do ? And if there is a standard implementation why don't it being included in Hibernate jar itself?

Answer 1

There's an answer here that might suffice.

Looks like they want developers to write their own by design, because the number of possibilities to cover is too large.
