As the previous message points out you have to do the uninstall of kaffe and you can install the newer j2re everything is competely correct, but step 8 reads
-------------- snip ----------------
8)Now if you try to install LimewireLinux you should get an error saying that it cant find VM on your system.
Type the following line and then you should be able to install LimeWire

export JAVA_HOME=/usr/java/j2re1.4.0
export PATH=$PATH:/usr/java/j2re1.4.0/bin
-------------- snip ----------------
I would add that you need to verify that path, ie
ls -al /usr/java/j2re1.4.0/bin
and
ls -al /usr/java/j2re1.4.0

the newer j2re's path can be slightly different and doing as above on one using the newer versions will result in a no VM error still cause the path isnt correct
ie
JAVA_HOME=/usr/lib/jre-1.3.1_02
NOT
JAVA_HOME=/usr/lib/jre-1.3.1

I hope this helps someone as the previous messages helped me get to this point and yes, now i have limewire running on Mandrake 8.2
