How to Get Working Juniper Network Connect on OS X Mavericks

If you happen to use Juniper SSL and if you are using Mac, then you are very likely to stumble upon nice surprise when connecting to VPN with Java 1.7 or after Java update.

Error message when logging in via browser: Java plugin required.
If you click on greyed out area (missing plugin), you are redirected to Oracle Java webpage.
If you install Oracle Java 1.7 Juniper Network Connect won’t work. You need Java 1.6.

What you need to do is to enable old Apple Java.
It’s easy to fix it:
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

start Network Connect and you will be greeted with a window you missed so much.
