java - Need a client side API for determing geo location of IP addresses

Question

I need a client side API in either Java or Ruby. I would much prefer need this to be LOCAL only. Infact this might not even be an IP, but more of a database import. The thing is that I cannot make use of a web service based one as that is too much heavy I/O for me.

Note: By geolocation, all I really need is country/region at best. I would accept actual lat/long cordinates as well.

I was looking at these guys a couple months ago: http://www.maxmind.com/app/geolitecountry

It seemed OK, for my limited purposes.
