[Q] Problem with JSR 179 (Localization API) [WM] [GPS] - HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting

Hello.
I'm trying to write a program in J2ME on WM 6.5 (concrete HTC Leo) to locate the position using internal GPS receiver. The problem is that WM does not support JSR 179 Java package corresponding to the location API. Do you know maybe some way to attach the package to the environment WM (JBlend Java emulator). If not, is there some other way to communicate with the built-in GPS in J2ME?
It may be a simpler way to write a program in C #. Unfortunately, I haven't experience in C #. What library to use to get to the GPS?
Below is a basic code that I use to read longitude and latitude from a GPS receiver. It works for sure with the Nokia 5230, but probably also with other devices based on Symbian, as this is included in the package JSR 179.
Code:
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
import javax.microedition.location.*;
public class GPS_Speedometer extends MIDlet implements CommandListener {
private Form mMainForm;
private StringItem message;
public GPS_Speedometer() {
message = new StringItem("","");
Retriever ret = new Retriever(this);
ret.start();
mMainForm = new Form("GPS Speedometer");
mMainForm.append(new StringItem(null, "GPS Speedometer!\n"));
mMainForm.append(message);
mMainForm.addCommand(new Command("Exit", Command.EXIT, 0));
mMainForm.setCommandListener(this);
}
public void startApp() {
Display.getDisplay(this).setCurrent(mMainForm);
}
public void pauseApp() {}
public void destroyApp(boolean unconditional) {}
public void commandAction(Command c, Displayable s) {
notifyDestroyed();
}
public void displayString(String string) {
message.setText(string);
}
class Retriever extends Thread {
private GPS_Speedometer midlet;
public Retriever(GPS_Speedometer midlet) {
this.midlet = midlet;
}
public void run() {
try
{
while (true){
checkLocation();
Thread.sleep(5000);
}
}
catch (Exception ex)
{
ex.printStackTrace();
midlet.displayString(ex.toString());
}
}
public void checkLocation() throws Exception {
String string;
Location location;
LocationProvider location_provider;
Coordinates c;
Criteria cr = new Criteria();
cr.setHorizontalAccuracy(500);
location_provider = LocationProvider.getInstance(cr);
location = location_provider.getLocation(60);
c = location.getQualifiedCoordinates();
if(c != null ) {
double lat = c.getLatitude();
double lon = c.getLongitude();
double alt = c.getAltitude();
string = "\nLatitude: " + lat + "\nLongitude: " + lon + "\nAltitude: " + alt;
} else {
string ="Localization API failed.";
}
midlet.displayString(string);
}
}
}
I will be grateful for any help and suggestions.
