Can't start Serviio in Lubuntu

Hi,

Could anyone please help with some advice - I'm running Lubuntu 14.04.1 LTS. I've installed Serviio using the instructions found here: http://www.tylergale.com/?p=77 My problem is that I can't start Serviio. I've tried starting from the command line and from executing the files themselves from within the bin folder. Please see below for the message showed in XTerm:

damo@damo-ISTART-2390-AIO:~$ sh /home/damo/serviio-1.5.2/bin/serviio.sh

I'm using Java 7, update 80.

Thanks
