            helloJMFPlayer = Manager.createRealizedPlayer(url);
        } catch (Exception e) {
            System.out.println(" Unable to create the audioPlayer :" + e);
        }

        Component control = helloJMFPlayer.getControlPanelComponent();

        frame.getContentPane().add(control, BorderLayout.CENTER);
        frame.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent we) {
                HelloJMF.stop();
                System.exit(0);
            }
        });
        frame.pack();
        frame.setSize(new Dimension(200, 50));
        frame.setVisible(true);
        helloJMFPlayer.start();

    }

    public static void stop() {
        helloJMFPlayer.stop();
        helloJMFPlayer.close();
    }

    public static void main(String args[]) {
        HelloJMF helloJMF = new HelloJMF();
    }
}

Please help me in finding the error!!!!

Answer 1

You have given a mp3 file but jmf alone can't play mp3.
For that you have to use mp3plugin.jar file, download the jar and then add to classpath then try again and with your code you can play .wav files.
