Answer 1

You might want to solve a bigger problem. You ought not enter configuration data such as database connection information directly in your servlet.

Are you using Tomcat? You can simply use JNDI. You will be able to change database details and drivers without having to recompile your servlet.

Here is the Tomcat 7.0 JNDI Datasource HOW-TO shows various ways in which you can get a Connection to your database.

On that page, you have a code example of how to get a Connection (Oracle 8i, 9i & 10g -> Part 3), and how to write a MySQL specific configuration.

Make sure to download a correct MySQL jar and place it in your Tomcat's lib/ directory (or alternatively your WAR's WEB-INF/lib).
