JSR179:LocationProvider: Shutting down! and java.lang.SecurityException

Question

Hello,
I am a newbie both at Java ME and JSR-179 (Location based services). I am trying to create location based services but gets the following error:
JSR179:LocationProvider: Shutting down!
null - 6
java.lang.SecurityException

at unknownThe problem occures when trying to execute following line below: Location l = lp.getLocation(60);Additional information:
1. The output "null - 6" above is from my Catch-block. That's how I know at which row the error occurs
2. The application works in WTK.
3. The problem occures when I am using the SEM Device Explorer and doing on device debugging. Not sure if that is related to that.
4. If I am running the directly on the phone it works. Well, not neccessarily if I have tried running it from the Device Explorer, guess it wont work because something happened while using the Device Explorer. And when I am trying to use the application on the phone and it hangs, the only thing I can do is to restart the phone. The phone hangs when the "phone" asks if the application should have access to the resources on the phone.
5. Have I missed something, but could it be some place where I can read about all these things how it works?
Please let me know if I should provide more information. I have noted down everything I can think of. I really need to get this going asap.
My code looks as follows:
package hello;
import java.util.Calendar;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import javax.microedition.location.Coordinates;
import javax.microedition.location.Criteria;
import javax.microedition.location.Location;
import javax.microedition.location.LocationProvider;
public class HelloMIDlet extends MIDlet implements CommandListener {
private int err = 0;
private Command exitCommand;
private Display display;
StringItem errTest;
public HelloMIDlet() {
display = Display.getDisplay(this);
exitCommand = new Command("Exit", Command.EXIT, 0);
public void startApp() {
try{
StringItem t = new StringItem("First: ", "Baseline");
StringItem t2 = new StringItem("After Criteria cr: ", "0");
StringItem t3 = new StringItem("After cr.setHoriz: ", "0");
StringItem t4 = new StringItem("After LocationProvider: ", "0");
StringItem t5 = new StringItem("After Location l: ", "0");
StringItem t6 = new StringItem("After Coordinates c: ", "0");
StringItem t7 = new StringItem("After double lat: ", "0");
StringItem t8 = new StringItem("After double lon", "0");
errTest = new StringItem("Error", "0");
    err = 1;
Form form = new Form("TestLocation");
form.append(t);
form.append(t2);
form.append(t3);
form.append(t4);
form.append(t5);
form.append(t6);
form.append(t7);
form.append(t8);
form.append(errTest);
    err = 2;
form.addCommand(exitCommand);
form.setCommandListener(this);
display.setCurrent(form);
long time = Calendar.getInstance().getTime().getTime();
t.setText(Long.toString((Calendar.getInstance().getTime().getTime())-time));
    err = 3;
    Criteria cr= new Criteria();
t2.setText(Long.toString((Calendar.getInstance().getTime().getTime())-time));
err = 4;
cr.setHorizontalAccuracy(500);
err = 5;
t3.setText(Long.toString((Calendar.getInstance().getTime().getTime())-time));
// Get an instance of the provider
LocationProvider lp= LocationProvider.getInstance(cr);
err = 6;
t4.setText(Long.toString((Calendar.getInstance().getTime().getTime())-time));
Location l = lp.getLocation(60);
err = 7;
t5.setText(Long.toString((Calendar.getInstance().getTime().getTime())-time));
Coordinates c = l.getQualifiedCoordinates();
err = 8;
t6.setText(Long.toString((Calendar.getInstance().getTime().getTime())-time));
if(c != null ) {
// Use coordinate information
double lat = c.getLatitude();
err = 9;
t7.setText(Long.toString((Calendar.getInstance().getTime().getTime())-time));
double lon = c.getLongitude();
err = 10;
t8.setText(Long.toString((Calendar.getInstance().getTime().getTime())-time));
}catch (Exception e){
System.out.println(e.getMessage() + " - " + err);
errTest.setText(e.getMessage() + " - " + err);
e.printStackTrace();
public void pauseApp() {
public void destroyApp(boolean unconditional) {
public void commandAction(Command c, Displayable s) {
if (c == exitCommand) {
destroyApp(false);
notifyDestroyed();
}Would be most greateful if anyone could help ou, it's a bit stressful to dump into problems like this without any clue how to solve it.
Thank you in advance!

Answer 1

...Is there any other way to do on-device debuging not using Sony Ericsson Device Explorer?Well I think it depends on whether device supports debug wire protocol like KDWP or JDWP. If it does then you might try debugging with Netbeans Mobility or with Wireless Toolkit ...
