You'd be better off asking this on the WEB400-L mailing list, I think,
but I'll give you a basic rundown:

1. You have to have a static IP address
2. You have to own the domain name
3. You have to point the domain to your static IP address

If your iSeries is wide open to the Internet, that's all you need.
However, most people these days configure their iSeries with an internal
address, usually a 10.x.x.x address, which is "non-routable", meaning it
can't be accessed from the Internet.  Then, they use a router with
something called NAT (Network Address Translation) to translate the
static IP address (from step 1 above) to the appropriate 10.x.x.x
address.

The biggest problem in your case is that typically requests come in on
port 80, not port 8080.  You will either have to use
http://www.domain.net:8080 to access your machine, or you will have to
set up Tomcat to listen on port 80 rather than 8080.  I personally don't
know of any routers that do port mapping as well, though someone more
versed in this subject could certainly help.  And my guess is they are
likely to reside on WEB400-L (or perhaps even MIDRANGE-L).
