Recording Audio in SunWTK2.5 Getting Error ..........

Question

Hi Every body,
I would like to Record Audio in Sun WTK2.5, i wrote code like below
public class SaveCapturedAudioMIDlet extends MIDlet implements CommandListener{
// the display items
private Display display = null;
private Alert alert = null;
private Command exitCommand = null;
// players and controls
private Player capturePlayer = null;
private RecordControl rControl = null;
private Player playbackPlayer = null;
String test = System.getProperty("fileconn.dir.photos").toString();
String url = test.substring(0, test.lastIndexOf('/')-6)+"sound/record/";
private boolean error = false;
public SaveCapturedAudioMIDlet() {
// create the display
display = Display.getDisplay(this);
alert = new Alert("Message");
alert.setTimeout(Alert.FOREVER);
alert.setString("Capturing for 10 seconds. Say something intelligent!");
exitCommand = new Command("Exit", Command.EXIT, 1);
alert.addCommand(exitCommand);
alert.setCommandListener(this);
try {
// create the capture player
capturePlayer = Manager.createPlayer("capture://audio");
if (capturePlayer != null) {
t;white-space: pre;">
// if created, realize it
capturePlayer.realize();
// and grab the RecordControl
rControl = (RecordControl)capturePlayer.getControl(
"RecordControl");
// set the alert as the current item
display.setCurrent(alert);
// if it is null throw exception
if(rControl == null) throw new Exception("No RecordControl available");
// and set the destination for this captured data
rControl.setRecordLocation(url+"test1.wav");
} else {
throw new Exception("Capture Audio Player is not available");
} catch(Exception e) {
error(e);
public void startApp() {
if(error) return;
try {
// first start the corresponding recording player
capturePlayer.start();
// and then start the RecordControl
rControl.startRecord();
// now record for 60 seconds
// Thread.sleep(10000);
Thread.sleep(10000);
// stop recording after time is up
rControl.stopRecord();
// commit the recording
rControl.commit();
// stop the Player instance
capturePlayer.stop();
// and close it to release the microphone
capturePlayer.close();
playbackPlayer = Manager.createPlayer(url+"test1.wav");
playbackPlayer.start();
} catch(Exception e) {
error(e);
public void pauseApp() {
public void destroyApp(boolean unconditional) {
if(capturePlayer != null) capturePlayer.close();
if(playbackPlayer != null) playbackPlayer.close();
public void commandAction(Command cmd, Displayable disp) {
if(cmd == exitCommand) {
destroyApp(true);
notifyDestroyed();
// general purpose error method, displays on screen as well to output
private void error(Exception e) {
alert.setString(e.getMessage());
alert.setTitle("Error");
display.setCurrent(alert);
e.printStackTrace();
error = true;

private RecordControl rControl = null;
rControl.setRecordLocation(url+"test1.wav");
//...... i got the exception like below:::
" java.lang.SecurityException: Application not authorized to access the restricted API "
...Did you *set permissions required for setRecordLocation* ?
If needed, [click here|http://java.sun.com/javame/reference/apis/jsr135/jsr135_rp.html] for details on MIDP/MMAPI security permissions for audio recording (capture).
Instructions on how to set these [permissions in Wireless Toolkit|http://i44.tinypic.com/24e5i5j.jpg] are provided in documentation (section +6.1 Permissions+ in WTK 2.5.1 User Guide ).
