Hi All,

Hi!

I can't figure out how to implement custom hibernate connection
configuration in tapestry 5. Till now I used hibernate.cfg.xml file, but  
I want to change database any time the new user log in.

This is a very specific scenario and Tapestry-Hibernate was built to cover  
the most common ones. You can use Tapestry-Hibernate code as the starting  
poing of you own code.

Do You think it is posiible to
change this Session object on the fly and also 2 different user will be  
able to work on 2 different databases simultaneously?

You could decorate the Session service and return a completely different  
Session for each different user, but I'm not sure it would work.

One more thing is how to implement my own HibernateConfigurer and take
advantage of contributeHibernateSessionSource method. I really don't
understand this. Tapestry wants me to create my own
WidgetHibernateConfigurer class that defines:

configuration.setProperty("hibernate.connection.driver_class",
"org.postgresql.Driver");

No. Think of HibernateConfigurer as a Configuration post-processor.
