Tried what you guys have been saying about JRE

Before the great crash of 2002, I was happily using Lime Wire to download songs and such. Well, the way I got JRE working before was because of the command:

PATH=$PATH:/usr/java/jre1.3.1_03/bin/
export PATH

Thats what I was told to do in the newsgroups, and I tried it this time, and it dosn't work this time. (Yes, version information is correct) Any suggestions here? Let me go ahead and give you the error I got this time:

[rory@home Documents]$ sh LimeWireLinux.bin
