Current latitude and longitude in a BlackBerry app - blackberry

Question

I want to get the user's latitude and longitude in my BlackBerry app, and then generate the maps according to it.
How can I do that?
my code is:
import java.util.Timer;
import java.util.TimerTask;
import javax.microedition.location.Criteria;
import javax.microedition.location.Location;
import javax.microedition.location.LocationListener;
import javax.microedition.location.LocationProvider;
import javax.microedition.location.QualifiedCoordinates;
import net.rim.device.api.system.Application;
public class GPS_Location
{
private String log;
double longi;
double lati;
public GPS_Location()
{
new LocationTracker();
}
public boolean onClose()
{
Application.getApplication().requestBackground();
return false;
}
class LocationTracker extends TimerTask
{
private double longitude, latitude;
private Timer timer;
private LocationProvider provider;
Criteria cr;
public LocationTracker()
{
timer = new Timer();
cr= new Criteria();
resetGPS();
timer.schedule(this, 0, 60000);
}
public void resetGPS()
{
try
{
provider = LocationProvider.getInstance(cr);
if(provider != null)
{
/*provider.setLocationListener(null, 0, 0, 0);
provider.reset();
provider = null;*/
provider.setLocationListener(new MyLocationListener(), 3, -1, -1);
}
//provider = LocationProvider.getInstance(null);
} catch(Exception e)
{
}
}
public void run()
{
System.out.println("********************");
}
private class MyLocationListener implements LocationListener
{
public void locationUpdated(LocationProvider provider, Location location)
{
if(location != null && location.isValid())
{
QualifiedCoordinates qc = location.getQualifiedCoordinates();
try
{
lati = location.getQualifiedCoordinates().getLatitude();
System.out.println("********************latitude :: "+lati);
longi = location.getQualifiedCoordinates().getLongitude();
System.out.println("********************longitude ::"+longi);
}
catch(Exception e)
{
}
}
}
public void providerStateChanged(LocationProvider provider, int newState)
{
//LocationTracker.this.resetGPS();
if(newState == LocationProvider.TEMPORARILY_UNAVAILABLE)
{
provider.reset();
provider.setLocationListener(null, 0, 0, -1);
}
}
}
}
}

A Google result (coincidentally Stack Overflow) reveals the API call getLocation(). This may provide you with a starting point for retrieving the longitude and latitude.
Addition; the following may be helpful (from a subsequent Google search using terms based on your comment): http://www.blackberryforums.com/developer-forum/133152-location-api.html. I would quote some of the code, but there is a fair bit of information there. Let's just hope the link remained valid, or you post your solution when found :)
