title: Can java web start run on a device without JRE?
body: <p>I have been learning about Java web start and got interested in its features. But can my Java app downloaded and run from browser run on a device without a JRE(Java environment) installed?</p>
  
  <p>I have tried download a sample jar from browser with Java web start but my app can't run.</p>
  
  <p>Second question: Is there a feature in Java web start to check for an installed JRE and automatically setup the environment?</p>
