But it fails, why?
Probably a combination of reasons. First, the IP address shouldn't be your loopback address, but the IP of your machine itself. Second, you need to make sure that your X display manager is accepting incoming connections. At a prompt, type in "ps -ef | grep -i listen". If you see something like:
/usr/bin/Xorg -br :0 vt7 -nolisten tcp -auth /var/lib/xdm/authdir/authfiles/A:0-lRdKTb
then your X server isn't accepting incoming connections. Note the "nolisten" argument. There are many how-tos on how to let Debian accept incoming X connections, and this has been dealt with on this site many times as well...give a quick search, don't want to type up the same thing again.
Also, since you're paying for Oracle support, you can get help from them.
