      !!! KUBUNTU - KDE desktop !!!

      A DESCRIPTION OF THE PROBLEM :
      The Desktop class apparently is only looking for a Gnome browser. It does not try to look for Mozilla, FireFox or even Konqueror:-( So it fails when you don't run on a Gnome desktop.

      [pid 15878] execve("/export/home/marcow/bin/gnome-www-browser", ["gnome-www-browser", "http://www.sun.com"], [/* 46 vars */]) = -1 ENOENT (No such file or d
      irectory)
      [pid 15878] execve("/usr/local/sbin/gnome-www-browser", ["gnome-www-browser", "http://www.sun.com"], [/* 46 vars */]) = -1 ENOENT (No such file or directory
      )

      But I could not find any way to influence that behavior short of creating a symlink. No documentation or anything for what the browse action is actually looking:-( The IOException is not very helpful either:-(

      I gave this a high severity because it's not easy to find out what's wrong and how to fix it. I originally ran into this problem with NB 6.0/trunk. So other people will probably have the same problem.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Compile and run the test case on a system without any gnome-www-browser.


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Open a browser.
      Or give a useful error message if it can't find a browser.
      ACTUAL -

      java.io.IOException: Failed to show URI:http://www.sun.com
              at sun.awt.X11.XDesktopPeer.launch(XDesktopPeer.java:75)
              at sun.awt.X11.XDesktopPeer.browse(XDesktopPeer.java:64)
              at java.awt.Desktop.browse(Desktop.java:368)
              at javaapplication1.Main.main(Main.java:33)


      REPRODUCIBILITY :
      This bug can be reproduced always.

                  }
              }
          }
      }


      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      Create a a gnome-www-browser as a symlink to the browser of choice.
