title: Glassfish 3.1.2 and Eclipse
body: <p>I just downloaded the Glassfish version 3.1.2, this is not yet an official release.
  I need this version because my web application is using websockets.
  The problem I have now is with the Glassfish plugin for eclipse, he is not recognizing the new Glassfish Version.
  With the Glassfish Version 3.1.1 in Eclipse everything works fine.
  I am using Oracle Glassfish Server Tools (Eclipse plugin ) version 2.0.0.20111104904 from Oracle(last version I could download).
  If I try to add a new Server Runtime Environment in Eclipse for the Glassfish 3.1.2 I get the error:
  There is no valid GlassFish installation in the specified directory...
  I need everything to be able to debug my web application in Eclipse.</p>
  
  <p>Anyone know what the plugin is checking ?
  There is any change to trick the plugin so will run with Glashfish 3.1.2 too ?</p>
