[wplug] setting up firefox to use usbdisk java?

[Zach Uram]

I need to access my VPS's VNC over the web but when I try to connect
it says I need a plugin and prompts me to manually install a Java
Runtime Environment (JRE). I only have like 10MB of space on the
ramdisk I run (I use LiveCD since my hard disk controller died and my
BIOS is not USB-aware) so I downloaded jre-6u12-linux-i586.bin and
unpaced it on my usbdisk:

$ ls /media/usbdisk/home/sdg/java/jre1.6.0_12

bin        javaws  LICENSE  plugin  THIRDPARTYLICENSEREADME.txt
COPYRIGHT  lib     man      README  Welcome.html

The firefox running off my LiveCD is 1.5.0.3 which stores its files in
/root/.mozilla/firefox in the ramdisk partition.

Does anyone know exactly how I can tell firefox to use the Java files
and plugins in /media/usbdisk/home/sdg/java/jre1.6.0_12 ?
