There are various options, like adding it to the classpath environment variable, putting the JAR to your JRE\lib\ext, or specifying it as a command line switch option. See a classpath explanation here:

(And on the link posted at the end of that comment: http://www.mindprod.com/jgloss/classpath.html)

The switch option is also explained in detail here:

You said compile and run. I gave it for run. The links contain the same for the compile command as well:

javac -classpath JARFilePath YourFileName.java
