The first exception, java.sql.SQLException, is the one you need to resolve first. It is telling you that you have not connected successfully to the database. Anything after that won't work, hence the subsequent exceptions. Solve that one first. Maybe the database is inaccessible from your computer, or your database user/password is incorrect, etc.
