Question

Where does Oracle (Sun) install their JDK/JRE on Mac OS X 10.8 Mountain Lion?

Answer 1

On my system, evaluating which java leads me to /usr/bin/java. This in turn is a symlink to:

/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java

In case it's relevant, java -version tells me I have 1.6.0_37 installed.
