How to stop the encoding ?plz see the code and correct it

Question

public class NewClass
    /** Creates a new instance of NewClass */
    public NewClass ()
        StateHelper sh=null;
        Processor p=null;
        try
            p=Manager.createProcessor (new URL ("file:///ring.wav"));
            sh = new StateHelper (p);
            p.configure ();
        catch (NoProcessorException ex)
            ex.printStackTrace ();
        catch (IOException ex)
            ex.printStackTrace ();
        p.setContentDescriptor (new FileTypeDescriptor (FileTypeDescriptor.MPEG_AUDIO));       
        TrackControl track[] = p.getTrackControls ();
        boolean encodingPossible = false;
        for (int i = 0; i < track.length; i++)
            try
                track.setFormat (new AudioFormat (AudioFormat.MPEG));
encodingPossible = true;
catch (Exception e)
track[i].setEnabled (false);
if (!sh.realize (10000))
System.exit (-1);
DataSource source = p.getDataOutput ();
MediaLocator dest = new MediaLocator ("file://ring1.mpg");
DataSink filewriter = null;
try
filewriter = Manager.createDataSink (source, dest);
filewriter.open ();
filewriter.addDataSinkListener (new DataSinkListener ()
public void dataSinkUpdate (DataSinkEvent e)
if(e instanceof javax.media.datasink.EndOfStreamEvent)
DataSink ds=e.getSourceDataSink ();
try
ds.stop ();
System.out.println ("finished write");
catch (IOException ex)
ex.printStackTrace ();
filewriter.start ();
catch (NoDataSinkException e)
System.exit (-1);
catch (IOException e)
System.exit (-1);
catch (SecurityException e)
System.exit (-1);
p.start ();
p.addControllerListener (new ControllerAdapter ()
public void endOfMedia (EndOfMediaEvent e)
Controller controller = (Controller) e.getSource ();
controller.stop ();
controller.deallocate ();
System.out.println ("finished run through");
public static void main (String[] args)
new NewClass ();
o/p is "finished run through",the EndOfStreamEvent never occurs.please correct if anything is wrong.when i manually stop the program then only the encoded file appears on the disk. this has to used from the other class and i cannot afford to use exit().help me.

Try this - it seems to work
public class NewClass
    Processor p = null;
    DataSink sink = null;
     /** Creates a new instance of NewClass */
    public NewClass ()
        try{
            p = Manager.createProcessor (new URL ("file:C:/WINDOWS/Media/Windows XP Startup.wav"));
            p.addControllerListener (new ControllerAdapter ()
                 public void configureComplete(ConfigureCompleteEvent e){
                    System.out.println ("ConfigureCompleteEvent");
                    Processor p = (Processor)e.getSourceController();
                    processConfigured(p);
                 public void realizeComplete(RealizeCompleteEvent e){
                    System.out.println ("RealizeCompleteEvent");
                    Processor p = (Processor)e.getSourceController();
                    processrealized(p);
                 public void controllerClosed(ControllerClosedEvent e){
                    System.out.println ("ControllerClosedEvent");
                 public void endOfMedia (EndOfMediaEvent e)
                    System.out.println ("EndOfMediaEvent");
                    Processor p = (Processor)e.getSourceController();
                    p.stop();
                 public void stop(StopEvent e){
                    System.out.println ("StopEvent");
                    Processor p = (Processor)e.getSourceController();
                    p.close();
            p.configure();
        }catch (NoProcessorException ex){
             ex.printStackTrace ();
        }catch (IOException ex){
             ex.printStackTrace ();
    private void processrealized(Processor p){
         MediaLocator dest = new MediaLocator("file:C:/Workspace/ring1.mpg");
         try{
              sink = Manager.createDataSink(p.getDataOutput(), dest);
             sink.addDataSinkListener(new DataSinkListener(){
                  public void dataSinkUpdate(DataSinkEvent e){
                       if(e instanceof EndOfStreamEvent){
                        System.out.println ("EndOfStreamEvent");
                            sink.close();
              sink.open();
              sink.start();
         }catch(Exception eX){
         p.start();
    private void processConfigured(Processor p){
        p.setContentDescriptor (new FileTypeDescriptor (FileTypeDescriptor.MPEG_AUDIO));       
        TrackControl track[] = p.getTrackControls ();
        boolean encodingPossible = false;
        for (int i = 0; i < track.length; i++){
             try{
                  track.setFormat (new AudioFormat (AudioFormat.MPEG));
          encodingPossible = true;
     }catch (Exception e){
          track[i].setEnabled (false);
p.realize();
public static void main (String[] args)
new NewClass ();
