How to re-enable Apple's Web plugin after updating Java?


Have you heard about the Apple’s latest Java updates? On installing Apple’s Java updates, it will remove Apple’s java Web plug-in and force you to Oracle Java Web site to download latest version of Java 7. But, there are many users who still want Java 6 for specific Web content. Thus, Apple is offering instructions for disabling the Java 7 runtime as well as re-enabling the Java SE 6 plug-in.


For this, you need to move the Java 7 plugin to a custom disabled plugins folder and then give a link to the Java 6 plugin which is embedded in Apple’s java framework. Using the following commands, this can be done in the OS X Terminal:

1. Make the folder for the disabled plugin:

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

2. Move the current plugin to the disabled folder (copy and paste both lines):

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

nternet\ Plug-Ins/disabled

3. Create a link to the embedded Java SE 6 Web plugin (copy and paste both lines):

sudo ln -sf /System/Library/Java/Support/Deploy.bundle/Contents/Resource\

s/JavaPlugin2_NPAPI.plugin /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin

After completing this task, relaunch your Web browsers to let the change takes place. Also, you can re-enable the Apple’s Java Web Start feature by creating a link to the web start program that is embedded in the JavaVM framework.

Run the following command:

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

It is noticeable that these commands make use of “Sudo” command which will ask you to be logged in as an administrator. When you run them, “sudo” command will ask you to enter your admin password but continuous use of “sudo” command will not ask you for password.

Additional Java updates will disable the Java SE 6 plugin again then you have to run this procedure for restoring Java functionality.
