going insane with the Exception in thread "main" java.lang. blah blah blah

Exception in thread "main" java.lang.NoClassDefFoundError

After hours of fighting with this stupid stuff I finally get my program to work on windows. I dig through all the BS posted about this error already (most of which is garbage info btw). Reinstalling everything on windows apparently did the trick and it could find whatever it was looking for. hurray right? not.

move over to the macintosh...... out of 14 jar files i found on the machine to try running only one of them did, one of my own. but then another application of mine that was setup the EXACT same way doesn't load. even the third party stuff doesn't load properly and this is with the most recent jre and jdk installed, and then reinstalled.

i'm confident this is an issue with the installation of jre/jdk on the macintosh but i'm about to blow the thing up, let alone fix it. i've tried downloading an ide right on the mac to compile and build there but lo-and-behold, the download is another jar file that doesn't load. convienent.

i have the .java .jar .class files all willing and able to go but obviously i'm still doing something wrong trying to run this on a mac. (Dear Sun, a nice "export to exe or app" feature would rock, kthnxbye) do i need to copy something somewhere? (if so, boooo @ java). better yet, is there an equivalent to the classpath stuff on a mac?

with this kind of stuff it's no wonder people dont want to develop for macs

If you are not familiar with the setup on on eplatform or another, you should consider to maybe check this out:
