title: Is it possible to provide security for war file?
body: <p>I have developed a web application which I am going to sell, but I face some security issues because I am going to provide a <code>.war</code> file to client machines and I found <code>.war</code> files can be easily extracted.</p>
  
  <p>How can one provide security for war files to avoid being copied or extracted?</p>
  
  <p>While searching I found <strong>Excelsior jet</strong> which converts web apps to native code but it's a trial version and I cannot afford its price so I want to know other alternatives.</p>
