forwarding, rewinding , stopping an audiostream using client server

[Olla89]

Hi Everyone!!
I would kindly like some help to be able to stop, forward and rewind the the wav file when pressing the respective buttons for it. n i would like to do that by 1st determining the current byte the sound that was played when button was pressed and then forwarding it or rewinding it based on that byte. The help is very much appreciated. Here is some of my code:-

Server Side- To Establish Connection :-

try{  
  
            welcomeSocket = new ServerSocket(4563);  
  
            while (true) {  
  
            clientSocket = welcomeSocket.accept();  
  
                 inFromClient1 =  
                        new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));  
  
                 outToClient =  
                        new DataOutputStream(clientSocket.getOutputStream());

Client Side- To Receive Connection and list of file names:-

try{  
  
            clientSocket = new Socket("localhost",4563);  
            outToServer =  
                    new DataOutputStream(clientSocket.getOutputStream());  
             inFromServer =  
                    new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));  
  
  
            outToServer.writeBytes(user + '\n');  
            outToServer.writeBytes(str.toString()+'\n');  
            //outToServer.writeBytes(str);  
  
  
            String fileNames[] = new String[20];  
  
            int count = (inFromServer.read());  
            for (int i = 0; i<count; i++)  
                fileNames[i] = inFromServer.readLine();  
            jList1.setListData(fileNames);  
            jList1.updateUI();  
  
            // clientSocket.close();  
  
        } catch (IOException e) {  
            System.err.println("Can not Connect");}

Client Side- To send selected file name to be played from Server upon play button is pressed.

try{  
            outToServer.write(jList1.getSelectedIndex());  
            playAudio();  
        } catch (IOException e) {  
            System.err.println("Error");}

Server Side- To send sound file.

class StreamThread extends Thread{  
  byte b[] = new byte[100];  
  
  
  
  public void run(){     
      
    {  
                try {  
                      outToClient.write(count);  
                      for (int i = 0 ; i >< count; i++)  
                      outToClient.writeBytes(fileName[i]+'\n');  
                      int cf = inFromClient1.read();  
                      System.out.println(cf);  
                        
                          FileInputStream fis = new FileInputStream(files[cf]);  
  
                         // byte[] b = new byte [100];  
                          int r = fis.read(b, 0, b.length);  
                          while( r != -1) {  
                              outToClient.write(b, 0, r);  
                              r = fis.read(b,0, b.length);  
                          }  
                          System.out.println("Streaming finished");  
                      }  
  
                catch(IOException e) {  
                          System.err.println(e);  
                          System.exit(1);  
                      }  
                      
    }  
  }  
}
