While using .available() to read the entire stream often just works on local files, or files embedded in the jar, there is a more reliable stream method.
public static byte[] getStreamBytes(final InputStream is) throws IOException {
final ByteArrayOutputStream baos = new ByteArrayOutputStream();
int bytesRead = 0;
while (bytesRead > -1) {
bytesRead = Math.max(is.available(), 1);
final byte[] buf = new byte[bytesRead];
bytesRead = is.read(buf);
if (bytesRead > 0) {
baos.write(buf, 0, bytesRead);
}
}
baos.flush();
baos.close();
return baos.toByteArray();
}
