From my application written in java I want to open a folder, using the operating system file explorer.
I use Desktop.open(new File(path))
This works fine on wind
I was running into what sounds like the same issue on Mint 13. From what I can tell, changes to mime handling for opening directories has broken the java Desktop api. I was able to work around the problem by editing
~/.local/share/applications/defaults.list
and adding this line
x-directory/normal=nautilus.desktop
I'm running Mint 13 Cinnamon with java version "1.7.0_05"
