the java errors means that you're using ANOTHER jre other than the one from SUN.

I couldn't find my way though the LimeWire17 script, so I made a simple one that will run locally, at least.

set myJrePath to the path where you have sun's jre instaled;
set myLimePath to your LimeWire directory.

good luck,

(don't forget to chmod 755 this script)

#!/bin/sh
# set the SUN's JRE PATH
myJrePath=/usr/local/jre1.3.1
# set the LIME install PATH
myLimePath=~/LimeWire

cd $myLimePath
$myJrePath/bin/java -cp $myLimePath/collections.jar:\
$myLimePath/LimeWire.jar:\
$myLimePath/.:\
$myLimePath/swing.jar:\
$myLimePath/lax.jar com.zerog.lax.LAX $myLimePath/LimeWire17.lax
