I cannot find any problems in the hibernate.cfg.xml file despite the error message. Would I receive this error if it cannot connect to the database or because there is something wrong with the configuration file itself? Here is my hibernate.cfg.xml file, we are using MySQL. I've replaced usernames and passwords.

Check the stack trace. It says: " Wrapped Exception: Could not create a DBCP pool. There is an error in the hibernate configuration file, please review it.

Hi Sergiu, I checked the logs. I see an access denied error that I didn't see on the error page. I'll go straight to the log files from now on.
