用这个简易的MP3播放代码，本地播放没问题，但是部署到linux后就无法播放，请问这是什么原因？路径是服务器上的绝对路径

public void testname() throws Exception {
}

private String filename;
private Player player;

public MP3Player(String filename) {
this.filename = filename;
}

public void play() {
try {
BufferedInputStream buffer = new BufferedInputStream(new FileInputStream(filename));
player = new Player(buffer);
player.play();
} catch (Exception e) {
System.out.println(e);
}
}

public static void main(String[] args) {

String urlString = "callout/059187517113N18618216211C20180528164749751B906101033211A.mp3";
MP3Player mp3 = new MP3Player(urlString);
mp3.play();

}
