Connecting a MySQL database (no replies)

Hi,

Sorry for the dumb newbie question. I hope it's an easy answer.

I'm working with a developer overseas on a website that uses a database and he just sent me the root folder to run in the tomcat server, so I can run the site on localhost. He uses a datanucleus parameters file to set the path and login info to the database.

I have MySQL server running and also tomcat. But for some reason the web app won't connect to the database.

Any ideas of things I should check?

Thanks!
