Play an audio file over HTTP

Question

Hello everybody,
I'm trying to play an audio file over HTTP protocol. The code is the following:
public class HTTPClientJMF {
     static String url = "http://localhost/audio/Reklam1.wav";
     static String urlFile = "file:///C://tmp/audio/Reklam1.wav";
      * @param args
     public static void main(String[] args) {
          // TODO Auto-generated method stub
          try {
               DataSource dataS = new URLDataSource(new URL(url));
               dataS.connect();               
               Player player = Manager.createPlayer(dataS);
               player.start();
          } catch (MalformedURLException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          } catch (IOException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          } catch (NoPlayerException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
}Now, if I'm trying to play the file from the local disk (+urlFile+ - using file protocol), everything goes well, but if I'm trying to play the same file from the network (using http protocol) I get the following exception:
javax.media.NoPlayerException: Cannot find a Player for: javax.media.protocol.URLDataSource@fa9cf
Can somebody tell me what I'm doing wrong?
Thank you!

Ah',..okay. I constructed the DataSource like follows:
Buffer mediaBuffer = new Buffer();;
          String mediaURL = "http://ares.inescn.pt/video/Reklam1.wav";
          URL url;
          try {
               url = new URL(mediaURL );
               InputStream in = url.openStream();
               BufferedInputStream bufIn = new BufferedInputStream(in);
               for (;;) {
                    int data = bufIn.read();
                    // Check for EOF
                    if (data == -1)
                         break;
                    else
                         mediaBuffer.setData(data);
               System.out.println(mediaBuffer.getLength());
               if (mediaBuffer.getLength() != 0) {
                    DataSource ds = new DataSource();
                    HttpStream[] httpStream = ds.getStreams();
                    System.out.println(httpStream.length);
                    httpStream[0].read(mediaBuffer);
                    ds.connect();
                    ds.start();                         
                    Player player = Manager.createPlayer(ds);
                    player.start();But I still cannot play an audio file (wav format) over the HTTP. Application starts but nothing happened.
I make the modification like you suggested. (into the DataSource, more exactly for method getStreams()).
I renamed as well the HttpDatasource into HttpStream.
Did you actually tried the code? I've been reading the instruction how to test the code but I did not be able to run the example.
