You'll need Java 6 update 10 (or higher) installed on your computer. (Run java -version to see what version you have - it should be jdk1.6.0_10 or higher.) Earlier versions of Java 6 can be used to create and save diagrams, but you won't be able to print. (download Java)
Copy /classes/cs329/violet/com.horstmann.violet-0.21.1.jar to your own computer (via scp - ask if you don't know how to do this).
Change to the directory where you put the jar file on your own computer and run as
java -jar com.horstmann.violet-0.21.1.jar &
You may need to specify the path to your java installation.
This should work on Windows and Mac as well as Linux. (On Windows you may be able to double-click on the jar file to run it.)
