title: Is it okay to update a Java web application by replacing just single class files?
body: <p>Sometimes, when we're doing small changes to our web apps, e.g. bug fixes, we don't build a whole new WAR-file each time, but merely replace just the affected class files in the exploded web app directory under <code>WEB-INF/classes</code> and restart the app.</p>
  
  <p>Is that okay?</p>
