Here is the link to the junit testcase I used, GeoLiteCityTest.java

MaxMind provides java classes, but not jars. So, I have created a maven project that can build the code and generate jars. Here is the GitHub Project https://github.com/snambi/GeoIP

If you need to use this library in your maven project, add the following dependency

   org.geomind
   geoip
   1.2.8

Add the following repository configuration, under "repositories" in the pom.xml

   geoip
