Answer 1

I think you have to ensure in at least one of following:

1. If you're running your WAR file in servlet container - you can place your driver into container's lib folder.
2. Driver (mysql-connector) is in WEB-INF/lib folder inside your WAR file.

If you're running with your IDE - ensure, that mysql-connector is added to your classpath. Way to do it depends on IDE.
