I am using the HibernateSessionRequestFilter described at:

https://www.hibernate.org/43.html

If something goes wrong then there is a catch-block where rollback is done etc.

In my web application the user, in case of an error, sees just a white page.
I would like to show the user some kind of error-page telling that
"some thing went wrong on the server".

So how do I redirect the user to a error-html page or something after an exception
has been caught in hibernate sessionrequest filter?
