The following instructions are valid for al SFS2X prior to version 2.12. See the last section at the bottom for more recent releases.
SmartFoxServer 2X comes with a geolocation API and database that are used mainly in the AdminTool’s Analytics module to aggregate and show statistics based on geographical positions. The API is not directly exposed to developers but since it’s been requested several times here is a quick recipe on how to use geolocation in your Extension code.
For starters we need to add lib/logs-analysis-app.jar to our project’s dependencies and import a couple of classes:
NOTE: starting from SmartFoxServer 2X v2.12, the com.maxmind.geoip.Country class has been replaced by com.maxmind.geoip2.record.Country; change the above import accordingly.
Next we instantiate and initialize the IpGeoLocator class:
IpGeoLocator geo = new IpGeoLocator();
This tells the geolocation service to load the relative database, located under SFS2X/data/. Finally we can test the service with an IP address:
String ipAdr = "184.108.40.206"; // wikipedia's IP
// Locate address
Country country = geo.locateIP(adr);
if (country == null)
System.out.println("Not found for address: " + ipAdr);
System.out.println(ipAdr + ": " + countrt.getName() + ", " + country.getCode();
Running the code results in this output:
220.127.116.11: United States, US
NOTE: it is important to always check that the returned Country object is not null. If it is, the geolocation service was not able to resolve the IP to a specific country.
» SFS2X 2.12.x and higher
SFS2X 2.12 introduced automatic geolocation for every client. The setting is configurable per-Zone from the AdminTool > Zone Configurator > Enable Geolocation.
When the service is active we can access the geolocation data with a few lines of server side code:
class MyHandler extends BaseClientRequestHandler
void handleClientRequest(User sender, ISFSObject params)
Country ctry = sender.getCountry();
if (ctry != null)
trace("User's country: " + ctry.getName());
trace("Country ISO code: " + ctry.getIsoCode());
