Adding "lib" to an installation that isn't expecting one isn't going to
make a jot of difference.

"server-side"?  It's all server side - I don't know what you mean by this.

Where *exactly* is the mysql driver jar?

If your provider has given you a mangled installation, you need to go
back to them to figure out what they've done to it.

If the server was 5.x.x and they upgraded it to 6.0.x then ask them to
state exactly what they did to upgrade it.

N.B.  Just swapping the jars out is the wrong approach.

N.B.  There are more than 3 config files; tomcat/conf contains others.
The catalina.properties file for example, which defines which
directories act as classloader repositories.
