In an application I developed with Java 8, I am trying to convert a .wav audio file received in Base64 format to PCM_SIGNED format. The code works fine in the local environment, but I get the following error on JBoss EAP 6.4:

The method I get error is as follows:
public void convertBase64ToPcmSigned(String base64Audio) throws Exception {
byte[] audioByte = Base64.getDecoder().decode(base64Audio);
try (InputStream inputStream = new ByteArrayInputStream(audioByte);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream()) {
// Get AudioInputStream from the input stream
AudioInputStream inputAudioStream = AudioSystem.getAudioInputStream(inputStream);
// Define the target audio format
AudioFormat sourceFormat = inputAudioStream.getFormat();
AudioFormat targetFormat = new AudioFormat(
AudioFormat.Encoding.PCM_SIGNED, // PCM_SIGNED format
8000.0f, // Sample rate
16, // Sample size in bits
1, // Channels (Mono)
2, // Frame size
8000.0f, // Frame rate
false // Big-endian
);
AudioInputStream convertedAudioStream = AudioSystem.getAudioInputStream(targetFormat, inputAudioStream);
File outputFile = new File("output.wav");
AudioSystem.write(convertedAudioStream, AudioFileFormat.Type.WAVE, outputFile);
} catch (UnsupportedAudioFileException | IOException e) {
throw new RuntimeException("Audio processing failed", e);
}
}

I manually converted the base64 part to a wav file myself and it came out with the following properties.
Encoding : PCM_SIGNED
Sample Rate : 40000.0 Hz
Sample Size : 16 bits
Channels : 1
Frame Size : 2 bytes
Frame Rate : 40000.0 frames/second
Big Endian : false
The error only occurs in JBoss EAP 6.4 environment. When I test locally, the files are processed and converted correctly.
What points should I check or what alternative solutions should I try to solve this problem? Is there any special configuration required to process audio files in JBoss environment?
I tried the following code to first convert the Base64 format data to a .wav file and then process it file-based:
File file = new File(sourceFilePath);
InputStream inputStream = new BufferedInputStream(new FileInputStream(file));
if (!inputStream.markSupported()) {
return;
}
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(inputStream);
AudioFormat sourceFormat = audioInputStream.getFormat();
AudioFormat targetFormat = new AudioFormat(
AudioFormat.Encoding.ALAW,
8000,
8,
sourceFormat.getChannels(),
1,
8000,
false
);
AudioInputStream convertedAudioInputStream = AudioSystem.getAudioInputStream(targetFormat, audioInputStream);
AudioSystem.write(convertedAudioInputStream, AudioFileFormat.Type.WAVE, new File(destinationFilePath));
inputStream.close();
audioInputStream.close();
convertedAudioInputStream.close();
I got the following error on this line: AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(inputStream);

After some effort I found the solution to the problem. JBoss manages libraries and packages with its own module structure. So, even “standard Java libraries” sometimes need an additional module definition. I didn't have sound and main folders under /opt/jboss-eap-6.4/modules/system/layers/base/javax
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="javax.sound">
<properties>
<property name="jboss.api" value="private"/>
</properties>
<dependencies>
<system export="true">
<paths>
<path name="javax/sound/sampled"/>
<path name="com/sun/media/sound"/>
</paths>
</system>
<module name="javax.api" export="true"/>
<module name="sun.jdk" export="true"/>
</dependencies>
</module>
In doing so, we are in a way telling JBoss “I need the classes inside the javax.sound package, I also need access to sub-packages like com.sun.media.sound and javax.sound.sampled.
2.In the WEB-INF folder of your application , add a jboss-deployment-structure.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<dependencies>
<module name="javax.sound" export="true"/>
<module name="sun.jdk" export="true"/>
</dependencies>
</deployment>
</jboss-deployment-structure>
It is not enough to define a module in JBoss; you also need to specify that the application should refer to this module (dependency). Jboss adds these to the classloader.
After these steps the UnsupportedAudioFileException error was resolved.
