My reason for finding this information was to remove an older version of the JVM. I think it is a good idea to leave the Apple versions of the JVM on the machine (1.4 to 1.6.x on my machine). There still may be some utilities and such that rely on these versions. But unneeded versions of Java 1.7 should be fair game.

The first utility configures general Java Settings. The second allows you to select which versions are active and which is the default.
Removing a JVMTo remove a version, use
rm -rto delete the desired directory of the version you no longer need. Remember using
rm -ras the super user is very dangerous so make sure you know what you are doing before attempting this.
