Help regarding Audio streams

Question

Hi
I am a final yr student currently working on my voice chat project. I have been facing a sets of problems in my project
The streams which i send from the client to the server(client and server running on the same computer with loopback address 127.0.0.1) are not played by the server properly
Some streams r played thrice and some r not played at all though all streams r received by the server
I am posting my client server program below
Plz help me
this is the client named CaptureSound1.java
import javax.media.*;
import javax.media.rtp.*;
import javax.media.protocol.*;
import javax.media.format.*;
import java.util.Vector;
import javax.media.protocol.*;

public class CaptureSound1
public static void main(String args[])
     System.out.println("Client Started");
     Capture capture = new Capture();
     capture.startcapturing();
     System.out.println("Recording");
class Capture implements SendStreamListener
     Processor p;
     DataSink sink;
     DataSource ds;
     RTPManager rtp;
     SendStream sendstream;
     Capture()
          p=null;
     public void startcapturing()
          try
          Format format = new Format("Linear");
          Vector vector = CaptureDeviceManager.getDeviceList(format);
          CaptureDeviceInfo info = (CaptureDeviceInfo)vector.firstElement();
          MediaLocator source = info.getLocator();
          p = Manager.createProcessor(source);
          while(p.getState() < p.Configured)
               p.configure();
          p.setContentDescriptor(new ContentDescriptor(ContentDescriptor.RAW_RTP));
          TrackControl track[] = p.getTrackControls();
          for (int i = 0 ; i < track.length ; i++)
          Format suppFormats[] = track.getSupportedFormats() ;
          if (suppFormats.length > 0)
          track[i].setFormat(suppFormats[0]) ;
          else
          track[i].setEnabled(false) ;
          //System.err.println(track[i].getFormat()) ;
          while(p.getState() < p.Realized)
               p.realize();
          rtp = RTPSessionMgr.newInstance();
          rtp.addSendStreamListener(this);
          SessionAddress clientadd = new SessionAddress(InetAddress.getLocalHost(),5052);
          rtp.initialize(clientadd);
          SessionAddress serveradd = new SessionAddress(InetAddress.getByName("127.0.0.1"),5050);
          rtp.addTarget(serveradd);
          p.start();
          ds = p.getDataOutput();
          PushBufferDataSource pbds = (PushBufferDataSource)(ds);
          PushBufferStream pbs[] = pbds.getStreams();
          for(int i = 0;i<pbs.length;i++)
               sendstream = rtp.createSendStream(ds,i);
               sendstream.start();
          }catch(IOException e)
               System.out.println("Input Output Exception");
          }catch(NoProcessorException e)
               System.out.println("No Processor Present");

Answer 1

Well I was able to resolve my prob by removing the while loop in server.java and instead of that adding Thread.sleep(50000); but another problem is disturbing me
Whenever i am connected to net and try to run my prog with the loopback address no voice transmission takes place but when i am disconnected form net and run the same program using eclipse IDE it works fine and the prog also doesnt work on LAN
PLZ help me
