Program hangs when instantiating a DataSource

Question

Hello everyone !
I am sorry to disturb you with a silly question. I have done some research but I am unable to solve this by myself. I am a JMF beginner, and I am trying to stream wav files with the RTP protocol. Sadly, I can't get to create a DataSource, because the program hangs here :
public Streamer(String rtpaddress, String filepath)
        mediaLocator = new MediaLocator(rtpaddress);
        System.out.println("-> Created media locator: '" +
                       mediaLocator + "'");
          try
               URL url;
               url = new URL("http://127.0.0.1/sound.wav");
               DataSource source = Manager.createDataSource(
                      new MediaLocator(url)); // Program hangs here!
              System.out.println("-> Created data source: '" +
                                     url + "'");
             // set the data source.
             setDataSource(source);
             System.out.println("-> Set the data source on the transmitter");
             // start the processor
             mediaProcessor.start();
             // open and start the data sink
             dataSink.open();
             dataSink.start();
          catch (Exception e)
                { // Exceptions, etc... }I am quite sure my mistake is obvious : still, I have spent a lot of time trying to figure it out and I haven't.
Thanks in advance for your help !

Does the output include any or all of..
"-> Created media locator: '" + mediaLocator + "'"
"-> Created data source: 'http://127.0.0.1/sound.wav'"
"-> Set the data source on the transmitter"?

// Exceptions, etc... ?
What happens here? An ideal situation would [dump the stack trace|http://pscode.org/javafaq.html#stacktrace]..
e.printStackTrace();
