It is, but you're killing yourself with your own logic. Two corrections
are all that are needed.

It needs to be commented because this is not a service that is built in
to xinetd.

Because when you connect to port 8181, it runs a program that tries to
write to port 8181, which runs a programs that tries to write to port
8181, that runs a program which tries to write to port 8181, (you get
the picture).
xinetd does the redirecting of the program to port 8181, so get rid of
the redirect and it will start working.
I will admit that I had to play with it a bit before I could figure out
what was happening. 'tail -f /var/log/messages' was most illuminating.
That was how I figured out that the "type=INTERNAL" line was choking
xinetd and making it exclude that service with:
