Pause and Stop implementation in streaming audio

Question

Hi,
I am building a program that transmits audio over a TCP connection(using ServerSocket and Socket classes). My problem is that I am not being able to correctly implement the 'Pause' and 'Stop' option. Let's go into more details:
When the "Play" button is clicked, following line is invoked:
   Play(){
     dataOut.write(fileToPlay.getBytes());
     // write the name of file requested to dataOut, and dataOut is the TCP socket's OutputStream
     //initilized as dataOut = dataSocket.getOutputStream
     controlOut.write( PLAY_REQUESTED_FILE);
     //an int argument, server interprets this and reads the dataOut
     //and sends the audio bytes after encoding
     Player P = new Palyer (dataIn, controlIn);
     PlayerThread pt = new Thread(p);
     pt.start();
}                    the Player class's run method is:
public void run() {
        stopReq = false;
     //here the line object is opened and started.
     int nBytesRead = 0;
     new Thread(stat).start(); //this thread gives continuos statistics of bandwidth used
     while (nBytesRead != -1) {
           nBytesRead = dataIn.read(buf);
           //some decoding of buf goes on here
            line.write(decoded, 0, decoded.length);
}          The server works in a very similar fashion:
     when the PLAY_REQUESTED_FILE command is recieved, if invokes this play method:
          File f = getFileName(dataIn); // this gets the file name from input stream of the sockt
     Streamer s = new Streamer(f, dataOut);
     StreamerThread st = new Thread(s);
     st.start();
          the Streamer class's run method is:
          while (fis.available() != 0 ) {
          fis.read(dataBuffer);
          //fis is the stream to read the File object passed to constructor
          //some compression happens here and then,
          dataOut.write(dataBuffer);
          please help me implement the stop and pause options(the client GUI has the pause and stop buttons in place).
     as always, help is greatly appreciated,
     thanks in advance

thank you for your reply captfoss, i see that you're always the first one to reply, i am really grateful for that.
yes, i have already written code for issuing the stop and pause command, but i don't know how exactly one should implement them. i mean, i sure there'll have to to be some sort of lock object on which notify( ) and wait( ) methods will have to called, but i am not being able to do that. . something similar (but not same) thing has been discussed here http://www.javalobby.org/java/forums/t18465.html at the end of the page, please help as i have tried everything i can and still it adamantly refuses to work..
