Jar to exe. Answer in http://viralpatel.net/blogs/2009/02/convert-jar-to-exe-executable-jar-file-to-exe-converting.html

Converting exe to a jar file is possible. But involves reverse engineering to discover what is in the exe, extract and do whatever you want with it. In my opinion, is not worth at all.
