I will take it to another level. I am using Mandrake 8.2 with Java blackdown version:

java version "1.3.1_04"
Java(TM) 2 Runtime Environment, Standard Edition (build Blackdown-1.3.1-04b-FCS)
Java HotSpot(TM) Client VM (build Blackdown-1.3.1_04b-FCS, mixed mode)

I put where I downloaded my j2sdk1.3.1-04b-FCS:

/usr/java/jdk1.3.1_04

into my PATH in my .bash_profile:

export JAVA_HOME=/usr/java/jdk1.3.1_04
export PATH=$JAVA_HOME/bin:$PATH

After doing that, I remove kaffe from my system but I have a dependency problem with my wizard packages. I do this command to keep that program around:

rpm -e kaffe --nodeps

This removes all instances of kaffe binaries from /usr/bin.

I next create soft links to the /usr/bin directory but blackdown has most of all of it's java commands (ie java, javac, etc) as symbolic links. Some people´s configuration will not allow that many symlinks.
the symlinks point to a "hidden" file called .java_wrapper. So I link this to my /usrbin directory like so:

ln -s /usr/java/jdk1.3.1_04/bin/.java_wrapper /usr/bin/java

After doing that, I execute the LImeWireLinux.bin installer:

./LimeWireLinux.bin

Installation works. Program installed, running, and functional. I discovered that I had to install the program as user instead of trying to set it systemwide as root.

Go to Sun Microsystems and download the latest java client (RPM) for Linux.
./j2re-1_4_0_01-linux-i586-rpm.bin
rpm -ivh j2re-1_4_0_01-linux-rpm
edit profile adding following text after the end of the current line starting with PATH= /usr/java/j2re1.4.0_01/bin

Log off and back on

D/L latest distro of LimeWire.Linx ... install it ./LimeWireLinux.bin

Browse to where you installed it ... usually /home/[user]/runLimeWire

Follow onscreen instructions.

Gee ... 7 steps ... not quite a 12 step program ... but I see what I can do to make the directions more complicated
