I got this error when trying to login if the database was not started up. The login page will display without the underlying database running, but you can't login.

I'm a newbee (pun intended) with the same problem. I know that I have MySQL started, but is hibernate required even in the MySQL preconfigured version? I'm on Linux. Thanks...
