//</editor-fold>




public void locateme () {

try { Criteria cr = new Criteria();
cr.setHorizontalAccuracy(500);
LocationProvider lp = LocationProvider.getInstance(cr);
Location l = lp.getLocation(60);
Coordinates c = l.getQualifiedCoordinates();
if (c != null) {

String lat = c.convert(c.getLatitude(),c.DD_MM);
if (c.getLatitude() > 0) {
lat = "E " + lat;
} else {
lat = "W " + lat;
}
String lon = c.convert(c.getLongitude(),c.DD_MM);
if (c.getLongitude() > 0) {
lon = "N " + lon;
} else {
lon = "S " + lon;
}
stringItem = new StringItem("Hello", "Hello, World!");
stringItem.setText("\nYour present location is \n" + lat + "\n" + lon);

}
} catch (Exception e) { //LocationException OR InterruptedException

}}

well you can poll the locationprovider every 5 seconds by using a timer
Coordinates c = l.getQualifiedCoordinates();

or even better you can use the LocationListener interface instead...
I would advise you to have a good look at thew JSR-179 API Javadoc, it isn't a big API so it would be wise to fully understand it's funcitonality...
