.au sound format is not working

Question

Hello everybody,
Infact this Alarm.java (attached) using sun proprietary API sun.audio classes, now these are deprecated so i want to replace it with java se 6 classes.
This Alarm.java is beeping the PC but not able to run alarm.au audio file and gives Following exception
Exception Occurred....java.lang.IllegalArgumentException: No line matching interface SourceDataLine supporting format ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame, is supported.
Kindly help to make it work with alarm.au
NOTE: i hav commented all those sun proprietary API sun.audio code and tried with the alternate code in the same Alarm.java
Thanks

You can try to convert alarm.au to a supported format.
Here is an example how to find available converters:
import javax.sound.sampled.*;
import java.io.File;
public class ShowConverters {
    public static void main(String[] args) {
        AudioFormat format = null;
        try {
            AudioInputStream in =
                AudioSystem.getAudioInputStream(new File("alarm.au"));
            format = in.getFormat();
        } catch (Exception e) {
            e.printStackTrace();
        AudioFormat.Encoding[] encodings =
            AudioSystem.getTargetEncodings(format.getEncoding());
        if (encodings.length == 0) {
            System.out.println("No available format converters.");
            return;
        for (AudioFormat.Encoding encoding : encodings) {
            AudioFormat[] formats =
                AudioSystem.getTargetFormats(encoding, format);
            for (AudioFormat toFormat : formats) {
                System.out.println("--> " + toFormat);
}Good luck.
