I run JBoss on Win2000, WinNT, and XP with no problem. In your case I would start by taking the error message at its word, and assume that there really is a problem with the format of the class file, and start looking at your build process to see what could be causing it to be built with a badly formatted class.

the problem not in XP or Win2000, the problem is in P4,
on server with P3 Xeon all works greate, and the same .ear does not works on P4.
