title: Is it possible to compile a Rails app to a Java VM JAR file?
body: <p>Essentially the only thing I can deploy to my deployment machine is a JAR file.  I can't install JRuby, nor can I install Glassfish or Tomcat.</p>
  
  <p>Is it possible to package up a Rails application (including Rails, vendored, of course) to a JAR file such that I can do</p>
  
  <pre><code>c:\my_server&gt; java rails_app.jar
  </code></pre>
  
  <p>and have it run WEBRick or Mongrel within the JVM?</p>
