Yes, I had that I am using Mandrake 8.2.

The program cannot find java in your path. I loaded the latest j2re as an rpm. if you find it in the package manager you will find it installed (Mandrake 8.2) - assuming you laoded it in the rpm manager in the first place at /usr/java.

Add it to your path including the bin location, I added /usr/java/j2re1.4.0/bin to the path. Then I ran the program in the directory where I had loaded it, using sh LimeWire.sh. from a terminal.

if you use printenv it will list your present path, copy it and add the location of the java bin appending to the path.
