title: Better compression for WAR/EAR files?
body: <p>Is there a way to better compress WAR files (which is basically a ZIP file containing a lot of other ZIP files, that contain java *.class files)?</p>
  
  <p>ZIP does not exploit inter-file similarities (and is quite old anyway).</p>
  
  <p>Some archivers uncompress files that are compressed with inferior method before archiving them (and restore the old state when unarchiving).</p>
  
  <p>This would be of course for archiving purposes, as application servers expect actual WAR/EAR files.</p>
