Heard of google? It's a useful website.

Simple example at
http://www.exampledepot.com/egs/javax.sound.sampled/StreamAudio.html

and to know more, the Sun tutorial at
http://java.sun.com/docs/books/tutorial/sound/sampled-overview.html

Bye.

import java.io.*;
import javax.sound.sampled.*;

public class Play {
    public static void main(String[] args) {
        try {
            AudioInputStream ais =
                AudioSystem.getAudioInputStream(new File(args[0]));
            AudioFormat af = ais.getFormat();
            System.out.println("Format: " + af.toString());

            int frameRate = (int)af.getFrameRate();
            System.out.println("Frame Rate: " + frameRate);
            int frameSize = af.getFrameSize();
            System.out.println("Frame Size: " + frameSize);

            SourceDataLine line = AudioSystem.getSourceDataLine(af);
            line.open(af);
            int bufSize = line.getBufferSize();
            System.out.println("Buffer Size: " + bufSize);

            line.start();

            byte[] data = new byte[bufSize];
            int bytesRead;

            while ((bytesRead = ais.read(data,0,data.length)) != -1)
                line.write(data,0,bytesRead);

            line.drain();
            line.stop();
            line.close();
        } catch (Exception e) {
            System.out.println(e.toString());
        }
    }
}

Thank you all

I was looking for somethin like "javax.xxx.SimpleSound.playWave(File
wavFile) throw xxx". But ... no way.
I have found some other resources on google, but the code from Knute
Johnson seams to be the simplest.

Thanks

Finally solved my problem

I uploaded my audio product under the following web site:
http://www.freimann.eu/eliphi/phi/setzkasten/
The audio - version lies under:
http://www.freimann.eu/eliphi/phi/setzkasten/Setzkasten_sound.jar

Thanks again for all your help

PS The code I finally used is the following:

       }
   }

   public static void playSampleFile(String name) throws Exception {
       playSampleFile(name, 0.0f, 0.0f);
