title: Why should I sign my JAR files?
body: <p>Why should I sign my JAR files?</p>
  
  <p>I know that I need to sign my client-side JAR files (containing Applets) so that special things like filesystem access can be done, and so that the annoying bit at the bottom of windows doesn't show, but why else? And do I need to sign my server-side JAR files containing Servlets, etc.?</p>
  
  <p>Some basic rules for when and when not to sign JARs would be appreciated - thanks!</p>
