Hi,

Have you tried to verify if Java plugin was enabled in your browser ? It 
has been automatically disabled in a recent update of Firefox (12), due 
to a security problem of this plugin already exploited in the wild. For 
Firefox, it is in Tools, plugins. So perhaps nothing to do with PVE 2.1. 
Here, I have PVE 2.1, and VNC console is working perfectly, but Java 
plugin is enabled...

BTW, why is your character policy so big and fat ? It is difficult to 
read...
