It sounds like you are not setting the DISPLAY variable properly.
Regarding 'xhost +' that must be run on the CLIENT machine which is
running a real X server.
Sometimes, the DISPLAY variable is automatically set for you via ssh
(try "echo $DISPLAY" after you login). If you get nothing, you can
try to figure out what you need to set it to by running "who am i",
which shows you what hostname or IP the system thinks you are coming
from. For instance:
root@kvm01:~# who am i
root pts/1 2011-08-23 06:27 (client01.mydomain.com)
You then set your DISPLAY variable to what the system thinks is your
host/ip (as above):
root#kvm01:~# export DISPLAY=client01.mydomain.com:0.0
Then test with "xclock". If xclock dosen't work then the issue is on
your client. If your client is a windows box then you could load
"cygwin" (free), and install the X server. If your client is a unix
box, open a shell and enter "xhost +". I also recently dumped cygwin
(on Windows) a use program called "MobaXterm Home v3.0" which is a
great X server.
Regarding your question "do I need to have full OFBIZ installed", I
would think not. On the server where ofbiz is installed, all you have
to do is set the DISPLAY variable to the target client(s), and you
should be able to launch multiple POS instances (in the background),
like this:
cd /ofbis_home
DISPLAY=client01.mydomain.com:0.0 java -jar ofbiz.jar -pos &
...
DISPLAY=client20.mydomain.com:0.0 java -jar ofbiz.jar -pos &
However, the above assumes that each client is running their own
Xserver and each of them has run 'xhost +'
