Compiler always gets different errors on each computer with same JDK

Question

I have the same version of JDK on my laptop and my desktop. My laptop is Windows 7 and my desktop is Windows XP. When I run my game on the desktop, it says cannot find or load main class client. When I run it on my laptop it finds it. I have the versions for java and jdk 1.7u4 set up correctly for each computer. And when I compile the game, I have errors on the desktop that I don't get on the laptop. I would post my code, but I know it's not a coding error, because it works on one computer, yet not the other one. I've checked all details a million times, even tried fixing the random false errors I get from compiling, but have had no progress. I don't want to always have to edit my game client off of my laptop because I host the game on my desktop. If anyone has had this problem before, please tell me how you solved it. If you've had it but can't solve it, at least let me know I'm not the only one this has happened to. I can't find any solutions with Google, and I've even tried using a different version of JDK.(1.7u1) So, if it's not java, it's not my game, it has to be my computer. What could cause my computer to act like this towards my game. And other things compile fine, it's just my game client that doesn't compile. So then again, would it be something about my game, even though it works on my laptop and use to work on my desktop?? This is so confusing.

In case it is because of my client, and now that I read over the compiler a few times again, it may be. So here are the errors:

How are you launching your application? From an IDE? From the command line? In either case, how is it setup? — James Kingsbery, Aug 03 '12 at 19:19
why are you compiling it in 2 different m/c? The error suggests it classpath issue — srikanth yaradla, Aug 03 '12 at 19:30

The compiler complains that it can't find the required class javazoom.jl.player.Player on the classpath. There must be a difference in the way you compile the application on the two different machines.

Don't look at different operating systems or Java SDK versions. Check the build process. Verify that you have the required library on both machines and the classpaths point to that jar file.
