Java Example

This example demonstrates how to use the Loqate Java API to verify and geocode an address. The code shows the basic workflow: initializing the server, opening a session, processing a record with Verify and Geocode, and outputting all address fields.

import com.loqate.*;
import java.io.*;
import java.net.*;
public class lqtSample
{
 static
 {
  System.loadLibrary("lqtjava");
 }
 public static void main(String args[])
 {
  // Loqate objects
  lqtServer srv = lqtServer.create();
  lqtInputRecord rec = lqtInputRecord.create();
  lqtProcessResult res = lqtProcessResult.create();

  // Initialize the server
  if (args.length > 0)
   srv.init(args[0]);
  else
   srv.init("../data");

  // Create the process list
  lqtProcessList lst = lqtProcessList.create();
  lqtProcessOptions opts = lqtProcessOptions.create();
  lst.add("Verify", opts);
  lst.add("Geocode", opts);

  try
  {
   // Open the Loqate session
   int session = srv.open();

   // Process data
   try
   {
    // Set the relevant Loqate values
    rec.set("Address1", "Via Nicolo'machiavelli 4");
    rec.set("Address2", "Trieste Italy");

    // Process the record
    srv.process(rec, lst, res);

    // Output the result
    System.out.println(res.getAccuracyCode());
    for (int i = 0; i < res.getCount(); i++)
    {
     System.out.println(res.getField(i, "Organization"));
     System.out.println(res.getField(i, "SubBuilding"));
     System.out.println(res.getField(i, "Premise"));
     System.out.println(res.getField(i, "Building"));
     System.out.println(res.getField(i, "PostBox"));
     System.out.println(res.getField(i, "DependentThoroughfare"));
     System.out.println(res.getField(i, "Thoroughfare"));
     System.out.println(res.getField(i, "DoubleDependentLocality"));
     System.out.println(res.getField(i, "DependentLocality"));
     System.out.println(res.getField(i, "Locality"));
     System.out.println(res.getField(i, "SubAdministrativeArea"));
     System.out.println(res.getField(i, "AdministrativeArea"));
     System.out.println(res.getField(i, "SuperAdministrativeArea"));
     System.out.println(res.getField(i, "PostalCode"));
     System.out.println(res.getField(i, "Telephone"));
     System.out.println(res.getField(i, "CountryName"));
     System.out.println(res.getField(i, "ISO3166-2"));
     System.out.println(res.getField(i, "Latitude"));
     System.out.println(res.getField(i, "Longitude"));
     System.out.println(res.getField(i, "GeoAccuracy"));
     System.out.println(res.getField(i, "Address"));
    }
    System.out.flush();
   }
   catch (Exception e)
   {
    System.out.println("Exception: " + e);
   }

   // Close the session
   srv.close(session);
  }
  catch (Exception e)
  {
   System.out.println("Exception: " + e);
  }

  // Destroy the process list
  lqtProcessList.destroy(lst);
  lqtProcessOptions.destroy(opts);

  // Tidy up
  srv.shutdown();
  lqtInputRecord.destroy(rec);
  lqtProcessResult.destroy(res);
  lqtServer.destroy(srv);
 }
