Java SE 6 Runtime unavailable on Mountain Lion

I don't follow you Carlo... My response was in regards to restoring Apple's Java 6 applet plug-in.

this may help. http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/mac-faq.html#revert

No, it doesn't help. That page has incorrect information.

Why do you say that?

It states that the folowing command restores Apple's Jave 6:

sudo ln -s /System/Library/Java/Support/CoreDeploy.bundle/Contents/JavaAppletPlugin.plugin /Library/Internet Plug-Ins/JavaAppletPlugin.plugin

But the correct command is:

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

Note that the source file is slightly different than the one mentioned in the Oracle instructions. They are also missing a backslash.

From my understanding... starting with Mountain Lion Apple dumps old version of java. There is this transition stage that both Apple and Oracle are offering updates. However if you installed Mountain Lion on your machine then it is your responsiblity to download the Oracle Java from the Oracle site.

Now from my understanding fromthe article located at (and I am not lookong at the command lines... I do not mess ith that at all); the last three questions are the most important. Especially the one that reads:

...Q: What happened to the Java Preferences app in Application -> Utilities?

A: The Java Preferences app was part of Apple Java installation and is not used by Oracle Java. Therefore, OS X releases from Apple that do not include Apple Java will not include Java Preferences.

One of the functions of Java Preferences was to set the current version of the JRE. Under Oracle Java, only a single version of the JRE can be installed at a time. For more information, see JRE 7 Installation for Mac OS X.

To access the Java Control Panel, click the Java icon in the System Preferences panel. If the Java icon is not present (under the Other category) in System Preferences, you do not have an Oracle JRE installed.

... (my take is that this app in the utlity folder is not needed anymore. Just the app now located in the system preferences.)

I downloaded the updated directly from the Apple support site:

http://support.apple.com/kb/DL1515

Seems safer than using the macupdate.com site!

I believe anyone that downloaded this file, will need to reinstall ML. Hence it is not availabe anymore on the Apple site. If you were able to capture the file before they removed it, I would suggest you reinstall ML by holding down command+R while the computer is starting up.

This did work for me to revert the plugin to 1.6.

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

Apple posted this solution a few days ago and it fixed my previously posted problem (http://support.apple.com/kb/HT5559). Since Apple posts have a way of disappearing, the steps are:

In an Administrator Account, open Terminal, located in the Utilities folder.

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

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

Enter password

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

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

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

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

You can use terminal commands out line in article ht5559 to activate java SE6 as sometimes it is disabled by java 7,

heres the commands

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

I have exactly the same problem on Lion and not Mountain Lion, but created a ticket before to read you, and obviously nobody has found an answer... Have you? That would be so helpful!!!

Je pense que voues etes francaise? J'ai re-installe Java SE 6, puis redemarrer l'ordi. Ca a marche pour moi...

Tout à fait :) Le problème est que je n'arrive pas à réinstaller java (avec le téléchargement du site d'Apple), lorsque j'essaye j'obtiens un message me disant qu'il est déjà installé, et lorsque je vérifie avec terminal, la réponse est que java n'est pas installé, alors je tourne en boucle :(...

Oui, j'ai eu le même problème, alors j'ai fais un cherche sur Google et j'ai trouvé un site ou j'ai pu téléchargé Java SE 6 (ou 7).

Voici un 'link'.

Very nice! This worked very well! Very good!
