Old school code :-(

Question

Hey,
I been writing my game and wanted to show somone my game. However i can only get the newer java vm to work on his computer. Well i been writing my code for an older version becuase JBuilder wouldnt configure properly.
Well, the game works but the buttons dont work and i get a white background instead of black in the newer java vm. but everything works in the old one.
Well i want to update my code to the newest java VM.
The one i been using is:
java version "1.2"
Classic VM (build JDK-1.2-V, native threads)
ok, i post my code and i be most thankfulif you can show me where i need to modify the code. There are images in the program which i feel are not needed, so if you wanna compile it and run it, just use random images or block the code that does it so it can be tested
OK, thanks in advance, sorry for the length of the program but i kinda kept it tidy and readable.
ALso sorry its not documented :-(

Answer 1

Did you get any compile errors?
Are you getting any messages/exceptions at runtime?
The same code, compiled with a jdk 1.2 works fine?
(( You've tested this.. (my thought is that maybe somewhere you changed something but didn't recompile that has no broken execution...) you've compiled those specific files with the old jdk, just to make sure))
