Re-Enable Apple provided Java applet plug-in
Authored by: agentx on Oct 25, '12 02:35:28AM

Many older Java programs will not run on Java 1.7 so you have to re-enable 1.6 plugin if you need Java to work for most older applets.

There are 2 parts here Updating the Apple Java core 1.6 to latest version with security patches. Apple decided to turn off Java in browsers and remove plugin which is OK for most but not for Business/power users/some kids games ;-) that require it.

here is a script to do it....once you have updated 1.6 and upgraded to Oracles 1.7 version.

Also if you use Crashplan you need to update the the Java path in Crashplan plist as not compatible with Java 1.7 ! This script will correct it.

You are incorrect. All older Java programs will run in Java 1.7. Java has always maintained a rigid backward compatibility policy.

Any Java app written in Java 1.1 or higher will run in Java 1.7.

You are right, but also wrong. There are many applets that are part of internal systems at offices that don't work on 1.7. I have run into a few cases myself and know of a few. It's nice to be able to go back to the old version sometimes. In some cases, it's as simple as the developer put and = in a version check rather than a >= so it messes up on older compatibility test.

I am in agreement that it "should" all work but i assure you in the real world of System Administration there are several things that do not work ! Hence my comment. Crashplan / Powerschool does not run yet on Java core 1.7 which is a serious PITA as i have it deployed on lots of machines.
