title: Instructions to setup Launch4j for jar file
body: <p>I have created my project in U:/myproject where all the java stuff is installed in C: Drive. the jar file i created through netbeans is in u:/myproject/dist/myproject.jar. Could some one provided me the clean instructions of how to setup the launch4j and do i have to create a .exe file first?</p>
  
  <p>or if i just sign the jar file, i will get this errror</p>
  
  <pre><code>output.exe is not a valid win32 application
  </code></pre>
