Exception in thread "main" java.lang.NoClassDefFoundError: com/zerog/lax/LAX
 

I'm using a Red Hat 7.2, download and install
j2re-1_4_0-beta3-linux-i386-rpm.bin from sun.com.
After I change the line 3 of the "LimeWireLinux.bin" file to PATH=$PATH:/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin:/usr/java/j2re1.4.0/bin:/usr/java/j2re1.4.0/lib
and when I run ./LimeWireLinux.bin a have this gift:
Exception in thread "main" java.lang.NoClassDefFoundError: com/zerog/lax/LAX

me too...
 

I had this exact error, I am in Mandrake 8.1 though.

What shows up when you type "java -version" into a console?

this shows up
 

when i run: java -version, i get:
java version "1.3.1_02"
Java (TM) 2 Runtime Environment, Standard Edition (build 1.3.1_02-b02)
Java HotSpot(TM) Client VM (build 1.3.1_02-b02, mixed mode)

also
 

by the way, the limewire 1.7 installer works, I tried it just to check, so it must be something new in the 2.1.1 or whatever the newest one is

DUH!!!! Stooopeeed me!!!

Okay, here's the deal. I'm the guy who posted earlier about setting your $PATH to the Java Virtual Machine.

1.) Assuming you have Sun's JRE installed, it would be in the following directory:

/usr/java/

The $PATH of course would be:

/usr/java/jre1.3.1_02/bin

2.) So now that we've established

$ echo $PATH
/bin:/usr/bin:/usr/X11R6/bin:/usr/local/bin:/usr/X11R6/bin:/usr/games:/usr/sbin:/usr/java/jre1.3.1_02/bin

that java is in your $PATH you're 1/2 way there.
IF you have a version of kaffe on your system, remove it (as root):

$ rpm -q kaffe

IF you have any version on there then remove:

$ rpm -e kaffe

(Or use your favorite GUI package manager)
===============

This seems to be installed by default on Mandrake. It'll cause conflicts!

Querying the version of java I have:

$ rpm -q jre-1.3.1_02
jre-1.3.1_02-fcs

Shows I have the latest version (although I thought I saw jre-1.3.1_03 out somewhere).

Now it works! Yay!!! Time to send in my donation ... :)

Uh.........
 

I have done all of that stuff. I still got that error. (I never had Kaffe installed BTW)

AAHHH. Too many people called Unregistered. I don't know who is who! Is this guy talking to himself? Heh. Anyways, I urge you to double check your Java installation, and make sure that you do NOT have any trace of Kaffe on your system (even by accident). And if that doesn't work, I urge you to try a different version of Java, possibly Sun's beta version 1.4. It's worth a try right? I just have a feeling that there is something wrong with your java setup. It just doesn't sound right to have sooo many successful Java installations on Mandrake 8.0 and 8.1 by other users, and then have you with this problem.

Did that
 

I did that stuff too, the Java install is fine, LimeWire just isn't installing. My JRE runs fine. If anyone has seen this error and solved it, please tell me.

I am none of the above unregistered people. I am using Red Hat 7.1 and I am getting the exact same error message. A fix would be great.
