I'm running Lion (10.7), and need to use JDK 6 for development, but previously I had installed JDK 7 and I can't seem to get it uninstalled.

I ran the JDK 6 installer and seems to be installed in /System/Library/Java/JavaVirtualMachines/1.6.0.jdk, and JDK 7 seems to be installed in /System/Library/Frameworks/JavaVM.framework/Versions/A

Somewhere along the lines my Java Preferences seems to have been deleted (not by me).

I tried to delete everything (as described here) in /System/Library/Java/JavaVirtualMachines/ and /System/Library/Frameworks/JavaVM.framework/ and then do a fresh install of JDK 6, but both JDK 6 and 7 came back!

Worse /usr/bin/{java,javac} point to JDK 7.

Does anyone know how I can delete JDK 7? (And maybe get back my Java Preferences?)

In most IDE's you can set the version of Java you want to use for development, if you have several versions installed. In Eclipse this is done under Preferences -> Java -> Installed JREs – tor Mar 14 at 4:16

Have you already tried the steps mentioned here?docs.oracle.com/javase/7/docs/webnotes/install/mac/… – ACB Mar 14 at 6:12
@ABC Ah you're right! JDK 7 is installed to /Library/Frameworks not /System/Library/Frameworks if you write up that answer I'll accept it. Thanks. – Petriborg Mar 14 at 11:08
