title: How can i Make an .exe file from jar file
body: <p>I developed a system using jdk 6. then i want to deploy that system to all kind of users(windows, linux). and also i want to create . exe file to install inside the client machine. this process should check whether there exists java(compatible version) inside the client machine. if there is not java inside the machine then installation process should provides facility to install it.and also software used to do that should be freely available.
  thanks in advance.</p>
