title: Simple "check for update" library in java
body: <p>I'm using Eclipse RCP, but, mainly because i have total control of the UI (removed all contributions, made Preferences from scratch, etc) i just cannot accept the complexity and demand of the included UPDATE MANAGER (also, i use PLUGINS not features, and the app Plugin must be EXTRACTED - though i could get arround this last issue).</p>
  
  <p>Anyway, on a first approach i just want to <strong>check IF there is a newer version of the app available.</strong></p>
  
  <p>The logical way would be to check against a file (xml?) on a server.</p>
  
  <p>Is there a good library and example out there?</p>
  
  <p>Thanks.</p>
