Help for MediaException:Missing protocol separator

Question

Hi all,
I am trying to record voice in the mobile phone and save it to a file using MMAPI functions.
I tried out the sample demo, "MMAPIExample" given in the NetBeans 5.0 Beta 2 with Mobility Pack 5.0 Beta 2.
I selected Simple Player->Audio Capture from default device->menu
->Start Recording from the emulator, after entering the record locater with "file:recording.wav", the screen will appear with the following text,
"MMA demos wants to record an image or audio clip. Is it ok to record?". Whenever I press the button for "Yes", the emulator is hang, it didn't go ahead to start recording.
I decided to write a MIDLET to solely test on the audio capture function with the following code:
try {
// Create a Player that captures live audio.
Player p = Manager.createPlayer("capture://audio");
p.realize();
// Get the RecordControl, set the record stream,
// start the Player and record for 5 seconds.
RecordControl rc = (RecordControl)p.getControl("RecordControl");
rc.setRecordLocation("file:voicerecording.wav");
rc.startRecord();
p.start();
Thread.currentThread().sleep(5000);
rc.commit();
p.close();
} catch (IOException ioe) {
} catch (MediaException me) {
System.out.println(me.getMessage());
} catch (InterruptedException ie) { }
The same situation occured as described earlier on. This time I was able to find out that a Media Exception was raised with the reason of missing protocol separator.
I am very new to writing J2ME program and I have no idea what is protocol separator.
Can anyone help me out with this problem?
Million thanks,
Siying

->Start Recording from the emulator, after entering the record locater with "file:recording.wav", the screen will appear with the following text,
"MMA demos wants to record an image or audio clip. Is it ok to record?". Whenever I press the button for "Yes", the emulator is hang, it didn't go ahead to start recording. and also it shows Warning: To avoid potential deadlock, operations that may block, such as networking, should be performed in a different thread than the
commandAction() handler. i have written the following code for recording and i also want to play that recorded one :
try {
     Player p = Manager.createPlayer("capture://audio");
          p.realize();
RecordControl rc = (RecordControl)p.getControl("RecordControl");     rc.setRecordLocation("file:///c/WTK22/appdb/DefaultColorPhone/filesystem/root1/audio.wav");
     rc.startRecord();
     p.start();
     try {
     Thread.currentThread().sleep(5000);
     } catch (InterruptedException ie) {}
     //stopRecorder();
     } catch (IOException ioe) {
     ioe.printStackTrace();
     } catch (MediaException me) {
     me.printStackTrace();
