Java Preferences app missing after java update

Did you look in the System Preferences?

There's still hope. The Java Preferences application was not removed from the Utilities folder on Snow Leopard after the *.37 update.

Funny. I was just showing a co-worker how to use Java Preferences to change java versions when the installer deleted it from under me. Now I can't get back to using Java 1.6.0_37 even though I know it is still installed.

I tried copying Java Preferences.app from another Mac. It took a few minutes to start up, but it finally ran and showed me the familiar options to choose java versions.

But... it didn't work. I'm still seeing

java version "1.7.0_06"

Java(TM) SE Runtime Environment (build 1.7.0_06-b24)

Java HotSpot(TM) 64-Bit Server VM (build 23.2-b09, mixed mode)

On the command line!

I know I can just change all the symlinks for /usr/bin/java (and other java-related binaries) to the 1.6 version, but there had got to be a better way....

Well I managed to workaround the issue by updating my symlinks. Here's what I did:

This changes the 'Current' symlink to point to the same version that 'CurrentJDK' is pointing to. This may or may not be the same on your system, so double check. This may or may not cause other problems, but so far I haven't seen any.

ITo undo the changes, just go back to the same directory and:

>sudo rm Current

>sudo mv Current.bak Current

Hope this helps!

Fortunately, i always clon my drive before an important update. It´s an horror that "java preferences " dissapears after the update, cause it allows to deactivate java in the system. Of course, i reverted to previous state.

Although I agree that it's probably wise to run your Mac Java free, there is no currently known Java malware that can impact OS X. All the attacks to date have been through the browser plug-in.

Running this does seem to change my default java from the command line, but it keeps all GUI launched java apps from actually opening. For instance I can't open IntelliJ Idea or even the Oracle Java Preferences Pane. If I undo the change things work fine again. I know this method used to work in earlier versions, but doesn't look like it is quite that simple now.

Does anyone have a different/better way of doing this?

Not sure what you want your end state to be, but Apple Just posted Java for OS X 2012-006: How to re-enable the Apple-provided Java SE 6 applet plug-in and Web Start functionality.

Looks like that takes care of web start and applets. I also need java 6 to be the default JRE/JDK on the system too. I've messed around with relinking the symlinks in /System/Library/Frameworks/JavaVM.framework/Versions but any changes there yield correct results from the command line but any java application that is launched fails to load.

I was able to get Java GUI apps (just Eclipse, actually. Haven't tried anything else yet) running by running the Java 7 installer again after changing the symlinks.

So you changed the symlinks to point to java 6, then ran the Java 7 installer?

The point is:

Aren´t you tired that we have to worry about this ****??? Apple begun to worry me years ago, but now makes me sick. I shouldn´t be worried abut this stuff¡¡¡
