WinXP and Win2k/98

I have successfully compiled my program on window XP but when i try to

compile the same program in either win2k and win87, it doesn't compile

and gives me the error of "cannot resolve symbol".

I am using the same java SDK on all the machines.

So what have i done wrong?

Thanks.
