for LimeWire to work you will need pure java installed on your machine, I suggest getting it from
ftp://metalab.unc.edu/pub/linux/deve....3.1/i386/FCS/
and download j2sdk-1.3.1-FCS-linux-i386.tar.bz2
file, then use archiver to decompress the file, it will create the directory j2sdk1.3.1 in your current directory, now open up kpackage found in K->System I believe (or open the XTerm and work with command line, don't be afraid of it you'll have to learn how to use it anyway) and remove kaffe suite if it is installed on your system, for console method try this
[this is your prompt]$ /bin/su
[this is your prompt]$ Password: type pass for root, you remember it don't you?
[this is your prompt]$ rpm -e kaffe
Now when you're still in console
[this is your prompt]$ mv ~yourusername/dir/where/download/stored/j2sdk1.3.1 /usr
This will move the j2sdk1.3.1 directory with all its contents into /usr directory on you system
{this is your prompt]$ exit
Now you'll need to adjust the $PATH environment variable, using advanced editor found under K->Editors
open .bash_profile file which is hidden and is in your home directory
you'll see the statement which initializes PATH and looks like
PATH=$PATH:/home/user_name/bin
append :/usr/j2sdk1.3.1/bin
so it will look like
PATH=$PATH:/home/user_name/bin:/usr/j2sdk1.3.1/bin
save file close, and now back to console
[This is your prompt]$ source .bash_profile
