Data Transfer using DataSink from DataSource to MediaLocator not working

Question

I wrote this pretty straightforward program to transfer from a DataSource to a MediaLocator and when i run it nothing happens. I waited for around 10 minutes and still nothing happened. I manually closed the program to see if any data has been transferred to the destination file but the destination file timpu.mp3 is empty. Can someone tell me why it isn't working?
import javax.swing.*;
import javax.media.*;
import java.net.*;
import java.io.*;
import javax.media.datasink.*;
import javax.media.protocol.*;
class Abc implements DataSinkListener
     DataSource ds;
     DataSink dsk;
     public void transfer() throws Exception
          ds=Manager.createDataSource(new MediaLocator(new File("G:/java files1/jmf/aa.mp3").toURL()));
          MediaLocator mc=new MediaLocator(new File("G:/java files1/jmf/timpu.mp3").toURL());
          dsk=Manager.createDataSink(ds,mc);
          System.out.println(ds.getContentType()+"\n"+dsk.getOutputLocator().toString());
          dsk.open();
          dsk.start();
          dsk.addDataSinkListener(this);
     public void dataSinkUpdate(DataSinkEvent event)
          if(event instanceof EndOfStreamEvent)
               try
                    System.out.println("EndOfStreamEvent");
                    dsk.stop();
                    dsk.close();
                    System.exit(1);
               catch(Exception e)
public class JMFCapture5
     public static void main(String args[]) throws Exception
          Abc a=new Abc();
          a.transfer();

Have thrown this together - so it's not pretty, but should give you an idea
