Just put it in the runtime classpath or add its path to the runtime classpath.

How to do it depends on how you're executing the program. If you're using java command in command console to execute a .class file, then use the -cp argument to specify the paths to classes and/or JAR files which are to be taken in the classpath. The classpath is basically a collection of absolute/relative disk file system paths where Java has to look for JAR files and classes.

Assuming that you've downloaded a .zip, you need to extract it and then look for a .jar file (usually in a /lib folder). For starters, it's the easiest to put the .jar in the current working directory and then execute your program (with the Class.forName("com.mysql.jdbc.Driver"); line) as follows:

java -cp .:mysql.jar com.example.YourClass

The . signifies the current path and the : is the separator (which I believe is correct for Ubuntu, on Windows it's ;).
