Java Trouble compiling maxmind geoip LookupService class

Question

I wonder if some one can please help as I am struggling to compile maxmind.geoip.LookupService.java

I have downloaded geoip-api-1.2.10.jar for inclusion in WEB-INF\lib and I have referenced it in my classes path, but it just won't compile.

I have compiled the following successfully so I'm a bit at a loss:

com.maxmind.geoip.Country
com.maxmind.geoip.DatabaseInfo
com.maxmind.geoip.Location
com.maxmind.geoip.Region
com.maxmind.geoip.timeZone

Can't seem to find a full set of compiled java classes for com.maxmind.geoip, any help would be much appreciated :-)

Answer 1

According to the MaxMind dev site, the API is available on the Maven Central Repository. You shouldn't need to compile anything unless you downloaded the source package.

I resolved this by downloading the latest java files from http://dev.maxmind.com/geoip/legacy/downloadable/ unpacked the folder and then opened a command prompt and typed the following:

cd source/com/maxmind/geoip/
javac *.java

I'm using jdk1.6.0_34 and all classes compiled with no errors.

I copied the com.maxmind.geoip folder to \WEB-INF\classes and downloaded geoip-api-1.2.10.jar and placed that in the WEB-INF\lib folder.

Finally I download GeoIP.dat from http://dev.maxmind.com/geoip/legacy/geolite/ and placed it in a new folder called GeoIP under webapps so that all my applications can use it.

The following code is to obtain the country code from a users IP Address:

import com.maxmind.geoip.*;
import java.io.IOException;

class CountryLookupTest {
    public static void main(String[] args) {
    try {
        String sep = System.getProperty("file.separator");
        String dir = "C:/Program Files/Apache Software Foundation/Tomcat 7.0/GeoIP";
        String dbfile = dir + sep + "GeoIP.dat"; 

        LookupService cl = new LookupService(dbfile,LookupService.GEOIP_MEMORY_CACHE);

        System.out.println(cl.getCountry("151.38.39.114").getCode());
        System.out.println(cl.getCountry("151.38.39.114").getName());
        System.out.println(cl.getCountry("12.25.205.51").getName());
        System.out.println(cl.getCountry("64.81.104.131").getName());
        System.out.println(cl.getCountry("200.21.225.82").getName());

        cl.close();
    }
    catch (IOException e) {
        System.out.println("IO Exception");
    }
    }
}

Hope this proves useful to others.

You have to download a Jar file called geoIP-api from this link to maven repository,In case you haven't downloaded the other Jar files from go this geoIP2 also don't forget to download the .DAT file from geoIP.dat. Then add the files to your project class path from project properties and then libraries finally add Jar in netbeans.

Now use this code:

    public String IpGeoLocation(String IP) {
        try {
            String dbfile = "C:\\Users\\User Name \\Documents\\NetBeansProjects\\IP Tools\\resources/GeoIP.dat";
            String location = "";
            LookupService cl = new LookupService(dbfile, LookupService.GEOIP_MEMORY_CACHE);
            location = cl.getCountry(IP).getName() + " " + cl.getCountry(IP).getCode();
            cl.close();
            return location;
        } catch (Exception e) {
                           return "Error";
        }
    }

I was able to find the country and country code only !!
