title: Smooth redeployment of WAR in production?
body: <p>I was wondering if there is a 'smooth way' of redeploying a Java WAR to a production server (no cluster, no OSGi)?</p>
  
  <p>All I can come up with is stop server, update file, restart server. And 10 minutes beforehand I need to display a maintenance warning on the site.</p>
  
  <p>What's your approach?</p>
