I have to play a .wav file from URL but getting UnsupportedFileException.
Below is the code.
public class LoopSound {
public static void main(String[] args) throws Exception {
HostnameVerifier hv = new HostnameVerifier() {
@Override
public boolean verify(String urlHostName, SSLSession session) {
System.out.println("Warning: URL Host: " + urlHostName
+ " vs. " + session.getPeerHost());
return true;
}
};
// Now you are telling the JRE to trust any https server.
// If you know the URL that you are connecting to then this should
// not be a problem
try {
trustAllHttpsCertificates();
} catch (Exception e) {
System.out.println("Trustall" + e.getStackTrace());
}
HttpsURLConnection.setDefaultHostnameVerifier(hv);
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
URL url = new URL(
"https://74.127.51.154/SiPbx/playback.php?access=subscriber&login=501%40mix&domain=mix.nms.mixnetworks.net&user=501&type=vmail&file=vm-20130109213353000125_netsapiens_com.wav&time=20130110170638&auth=de5dda39287604a88fc4b80c467e161d&submit=PLAY");
Clip clip = AudioSystem.getClip();
AudioInputStream ais = AudioSystem.
getAudioInputStream( url );
clip.open(ais);
clip.loop(0);
javax.swing.JOptionPane.
showMessageDialog(null, "Close to exit!");
}
private static void trustAllHttpsCertificates() throws Exception {
// Create a trust manager that does not validate certificate chains:
javax.net.ssl.TrustManager[] trustAllCerts =
new javax.net.ssl.TrustManager[1];
javax.net.ssl.TrustManager tm = new TempTrustedManager();
trustAllCerts[0] = tm;
javax.net.ssl.SSLContext sc =
javax.net.ssl.SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, null);
javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(
sc.getSocketFactory());
}
public static class TempTrustedManager implements
javax.net.ssl.TrustManager, javax.net.ssl.X509TrustManager {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public boolean isServerTrusted(
java.security.cert.X509Certificate[] certs) {
return true;
}
public boolean isClientTrusted(
java.security.cert.X509Certificate[] certs) {
return true;
}
public void checkServerTrusted(

throws java.security.cert.CertificateException {
return;
}
public void checkClientTrusted(
java.security.cert.X509Certificate[] certs, String authType)
throws java.security.cert.CertificateException {
return;
}
}
Below is the exception getting:
Exception in thread "main" javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input URL
at javax.sound.sampled.AudioSystem.getAudioInputStream(Unknown Source)
at LoopSound.main(LoopSound.java:35)
When I place the above URL in a browser's address bar, I'm able to download the file but I'm unable to play pro-grammatically. How can I solve this ?
EDIT
I changed the link to
https://74.127.51.154/SiPbx/playback.php?access=subscriber&login=501%40mix&domain=mix.nms.mixnetworks.net&user=501&type=vmail&file=vm-20130109213353000125_netsapiens_com.wav&time=20130110170638&auth=de5dda39287604a88fc4b80c467e161d&submit=PLAY
Now the above link is placed on the browser its downloading the file.
but when i execute the program getting new exception now.
Exception in thread "main" javax.sound.sampled.LineUnavailableException: line with format ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame, not supported.

Thanks in advance.
WAV is a container format (like a zip file is a container of many different files) so there is no actual WAV Audio format (LPCM is the most common). In this case your WAV contains a format called "CCITT u-Law" which isn't widely supported (its used for Cisco VoIP phones). I haven't seen a Java Library that can read it, but maybe knowing what to look for will help.
Below link helped me and I am able to play the wav file now.
How to play wav file with format CCITT u-Law
Edit
As per Millimoose comments, I am pasting some of the code from the above link to help others.
I am changing format of the wav file from CCITT U-Law to PCM_SIGNED which is the exact wav format.
URL url = new URL(
"https://sssss/xxxxx/playback.php?access=subscriber&login=501%40mix&domain=mix.nms.mixnetworks.net&user=501&type=vmail&file=vm-20130109213243000082_mixnetworks_net.wav&time=20130110170638&auth=c43ff32546e126be9b895bbf225b2e75&submit=PLAY");
AudioInputStream fis =
AudioSystem.getAudioInputStream(url);
System.out.println("File AudioFormat: " + fis.getFormat());
AudioInputStream ais = AudioSystem.getAudioInputStream(
AudioFormat.Encoding.PCM_SIGNED,fis);
AudioFormat af = ais.getFormat();
System.out.println("AudioFormat: " + 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.addLineListener(new MyLineListener());
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();
