title: Purpose of Glassfish's "generated" directory
body: <p>I need to better understand what goes into the "generated" directory inside a domain folder of Glassfish. I can see that deployed applications store some resource files in there, (xmls, properties, manifests...) but don't really understand why. Google was not very useful this time. Could someone point me to some relevant documentation? Thanks. </p>
  
  <p>Edit: I need to know these details because i want/need to delete this folder when restarting the server. </p>
