public class LookupService extends Object
The following code snippet demonstrates looking up the country that an IP address is from:
// First, create a LookupService instance with the location of the database. LookupService lookupService = new LookupService("c:\\geoip.dat"); // Assume we have a String ipAddress (in dot-decimal form). Country country = lookupService.getCountry(ipAddress); System.out.println("The country is: " + country.getName()); System.out.println("The country code is: " + country.getCode());In general, a single LookupService instance should be created and then reused repeatedly.
Tip: Those deploying the GeoIP API as part of a web application may find it difficult to pass in a File to create the lookup service, as the location of the database may vary per deployment or may even be part of the web-application. In this case, the database should be added to the classpath of the web-app. For example, by putting it into the WEB-INF/classes directory of the web application. The following code snippet demonstrates how to create a LookupService using a database that can be found on the classpath:
String fileName = getClass().getResource("/GeoIP.dat").toExternalForm() .substring(6); LookupService lookupService = new LookupService(fileName);
