I've got a glassfish server constructed with company default script. I Quickly have Liferay installed upon it. Liferay uses some predefined database to keep this content around the pages it shows. It's a company shared database have no idea where. How could I connect my liferay to some local clean database?

My setup is really a Glassfish with Liferay, the DatabaseI me is MySQL.

Thank you for any help!
