I do not see any Java Preferences.app in my Utilities directory.

I run a java -version in command line, there was nothing and prompted me to install version 1.6 from apple. It installs successfully.

I do not see any Java related application in my Utilities directory. I open up a web browser (Safari) and see "Missing Plug-in" in place of where any applet should be.

How do I enable the applet from my Java installation?

(On an aside, is it possible to use Java 7 JDK from Oracle such that the browser can recognize it and use it to resolve the "Missing Plugin issue", would prefer Java 7 over Java 6 anyday..)

Taken from this Apple support article titled,

"How to re-enable the Apple-provided Java SE 6 applet plug-in and Web Start functionality"

  1. Open Terminal, located in the Utilities folder.

  2. Enter this command, then press the Return or Enter key:

    sudo mkdir -p /Library/Internet\ Plug-Ins/disabled

  3. Enter this command, then press the Return or Enter key:

    sudo mv /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin /Library/Internet\ Plug-Ins/disabled

  4. Enter this command, then press the Return or Enter key:

    sudo ln -sf /System/Library/Java/Support/Deploy.bundle/Contents/Resources/JavaPlugin2_NPAPI.plugin /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin

  5. To re-enable Java SE 6 Web Start, enter this command, then press the Return or Enter key:

    sudo ln -sf /System/Library/Frameworks/JavaVM.framework/Commands/javaws /usr/bin/javaws

This does not appear to apply to Java 7... is it possible with Java 7 JDK too? (i would love to rid myself of 1.6) –  Charles Oct 31 '12 at 0:25
    
@Charles- Yeah, I'm not sure... The article did begin with this though, "If, after installing Java for OS X 2012-006 and Java 7, you want to disable Java 7 and re-enable the Apple-provided Java SE 6 plug-in, follow these steps." That's why I posted. I have not actually tried it myself. –  JoshP Oct 31 '12 at 2:01
