Java security warnings make it impossible to use Nanogong? Here's the solution.

Nanogong is one of the best things to happen to Moodle. The Nanogong plugin allows you to make voice recordings on your Moodle site. You can easily post recordings in Moodle forums or as a simple label activity.

But Nanogong didn't come without its own set of problems. Although Nanogong seemed to work fine on my Moodle 2.5 site, In the past I did get constant java security warnings  (Java 1.7.0_25 on my PC) - rendering it almost impossible for me to work with it.

The Beauty (Nanogong recorder for Moodle)
and the (Java) Beast

The irritating problem with java security warnings popping up everytime is a real deal-breaker when it comes to promoting the use of Nanogong. However, Nanogong is too good a plugin to not use on any Moodle site just because of some irritating and pesky pop up security warnings! So Nanogong is worth saving!
Here's the procedure to save the (your) day. Warning! Use at your own risk.

In Ms Windows 7,
1. Go to Start button
2. Click on Control Panel
3. You should see the Control Panel open up.

4. Look for the Java icon. If you don't or can't see the Java icon, type the word "Java" inside the Search Control Panel edit box, and press Enter.

See the image below:

When the Java window opens up,

5. Click on the Advanced tab
6. Scroll down to the "Mixed code (sandboxed vs trusted) security verification" section.
7. Check the "Disable verification (not recommended)" option

8. Click the OK button to save the Java settings.
9. Go back to your Moodle site.
10. Create another Nanogong recording in a Label or webpage.
11. No more Security warning pop-up?

Hope this helps. Oh by the way, earlier in this post I mentioned of a 'risk', right? Well the reason that "this option is not recommended" is because "this option" completely disables the software from checking for mixing trusted and untrusted code, leaving the user to run potentially unsafe code without protections. See So if some unsafe or malicious Java code fries your PC machine, don't ask me to travel to your part of the world to fix your machine, unless of course you pay for my airfare. You have been warned.
