Problemer med Geocoder i Java Swing

God ettermiddag, Jeg bygger et system til et akademisk prosjekt i Java Desktop. I dette prosjektet, trenger jeg å få en adresse (som 5th avenue, NY) og konvertere denne adressen til geografiske koordinater (breddegrad og lengdegrad) for å lagre dem i databasen. Disse koordinatene vises på et kart.

Jeg bruker JxMaps API, men jeg kan ikke tilpasse eksempel Geocoder koden gjøres tilgjengelig av dem. Uansett hva jeg gjør, koden fungerer bare ikke. Men i eksempelet, det fungerer.

Følger et tekstutdrag fra min kode (som er i pakken modell):

package model;
import com.teamdev.jxmaps.GeocoderCallback;
import com.teamdev.jxmaps.GeocoderRequest;
import com.teamdev.jxmaps.GeocoderResult;
import com.teamdev.jxmaps.GeocoderStatus;
import com.teamdev.jxmaps.InfoWindow;
import com.teamdev.jxmaps.LatLng;
import com.teamdev.jxmaps.Map;
import com.teamdev.jxmaps.Marker;
import com.teamdev.jxmaps.swing.MapView;

import dao.tableMapa;

public class Geocoder extends MapView {

private boolean performGeocode(String text) {
    public boolean s;
    // Getting the associated map object
    final Map map = getMap();
    // Creating a geocode request
    GeocoderRequest request = new GeocoderRequest();
    // Setting address to the geocode request
    request.setAddress(text);

    // Geocoding position by the entered address
    getServices().getGeocoder().geocode(request, new GeocoderCallback(map) {
        @Override
        public void onComplete(GeocoderResult[] results, GeocoderStatus status) {
            // Checking operation status
            boolean r=false;
            if ((status == GeocoderStatus.OK) && (results.length > 0)) {
                // Getting the first result
                GeocoderResult result = results[0];
                // Getting a location of the result
                LatLng location = result.getGeometry().getLocation();

                tableMapa p=new tableMapa();
                r = p.Geocodification(location, text);
            }
        }
    });
  }
}

Og dette er på Dao i pakken:

package dao;

import java.sql.Connection;
import java.util.ArrayList;
import javax.swing.JOptionPane;
import com.teamdev.jxmaps.LatLng;
import model.ModeloMySql;
import model.pontoColeta;
import controller.fabricaConexao;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

public class tableMapa {
    private ModeloMySql modelo = null;

    public tableMapa() {

        modelo = new ModeloMySql();
        modelo.setDatabase(projeto);
        modelo.setServer(localhost);
        modelo.setUser(root);
        modelo.setPassword(1234);
        modelo.setPort(3306);
    }

    public boolean Geocodification(LatLng location, String address){
        Boolean status = true;

        Connection con;
        con = fabricaConexao.getConnection(modelo);

        if (con == null) {
            JOptionPane.showMessageDialog(null, Failed to connect);
        }

        //String sql = UPDATE TABLE set(latitude=+location.getLat()+,longitude=+location.getLng()+ from pontocoleta where address=+address+;;
        String sql = UPDATE pontoColeta set latitude = ? ,longitude = ? from pontocoleta where address = ?;

        try {
            PreparedStatement statement = con.prepareStatement(sql);

            statement.setDouble(1, location.getLat());
            statement.setDouble(2, location.getLng());
            statement.setString(3, address);
            statement.executeUpdate();

        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            fabricaConexao.closeConnection(con);
            return false;
        }

        return true;
    }

    public ArrayList<pontoColeta> pontosSelect() {
        Boolean status = true;

        Connection con;
        con = fabricaConexao.getConnection(modelo);

        // testa se conseguiu conectar
        if (con == null) {
            JOptionPane.showMessageDialog(null, Failed to connect);
        }

        ArrayList<pontoColeta> pontos = new ArrayList<>();

        String sql = SELECT * from pontocoleta;
        pontoColeta p;

        try {
            PreparedStatement statement = con.prepareStatement(sql);
            ResultSet result = statement.executeQuery();

            while(result.next()){
                    p = new pontoColeta();
                    LatLng c = new LatLng(result.getDouble(latitude), result.getDouble(longitude));
                    p.setCoordinates(c);
                    p.setIdPonto(result.getInt(idPonto));
                    p.setDescription(result.getString(description));
                    p.setAddress(result.getString(address));
                    p.setPhone(result.getString(phone));  
                    pontos.add(p);

                } 
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            status = false;
        } finally {
            // Fecha a conexao
            fabricaConexao.closeConnection(con);
        }
        return pontos;
    }
}

Jeg kan ikke gjøre det arbeidet. Vennligst hjelp meg !!
