Java in Mac OS X 10.8 (Mountain Lion)

14 Aug

If you just upgraded your Mac to OS X Mountain Lion you probably noticed that Java Runtime Environment (JRE) is removed from your system. Apple has decided that Java is unnecessary for OS X and Mountain Lion upgrade process uninstalls Java but you can install it afterwards.

Apple theoretically tries to reduce the risk of security problems with Java just like we saw few months back with Flashback Trojan which infected over 700,000 Mac computers.

UPDATE:
OK, got it working now, short & sweet 2-step process for how to make Java work under 10.8:
1) From your terminal, run
java -version
you will get a Mac OS X dialog asking to install Java SE 6, click 'Yes'
2) From your browser, run
www.java.com/en/download/help/testvm.xml
you will get a Mac OS X dialog asking to enable Java plugins, click 'Yes'

    I understand their reasoning but I have java based software I use and don't want it broken.. I find more and more reasons not to upgrade to this new release..

    Same here.  I've already upgraded, and now I'm trying to access our Java-based JVMs.  So far it's been frustrating trying to get browsers to recognize Java under OS X 10.8
