Xwiki couldn't started using mySQL

Hello,
I changed the file hibenate.cfg.xml like explained here: http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationMySQL#Comments file
I wanted the Xwiki to use MySQL database.
After I started the xwiki, i have the following failure on my browser:

I don't know what is the problem.
It is really desponding.
Could someone bring me on the right way?

I attached the hiernate.cfg.xml.
