Yes it is, even though this is not programming related and you should ask on superuser.

What you need to do is forward your 8080 port through your router. if you're IP changes (you have a dynamic IP or a static IP, this is determined by your ISP) you can get a host name from dyndns and set up your router to update dyndns with your new IP when it changes. this will allow you to access your application like so: hostname.dynsns.org/your_app.

Alternatively, you can rent a hosted server and a domain name.
