Jar to Exe (on a Mac)

[Siggi]

Does anyone know how to convert a Jar to Exe on a Mac computer?
I only have Mac computer, but I want my software to work on a Windows as an Exe, not a Jar, because some noobs don't know how to open Jar files.
I already can make a Jar wrapper for Mac computer, but I want to make one for Windows.

^, Mac does not use exe therefore you have to use wine (winebottler) to open them. Also you don't need an converter, simply open the .jar using an archive program (winrar, winzip, archive utitlies(mac)). Then make an executable out of those files.
