尝试使用javazoom播放MP3文件，并显示错误消息“无法加载资源'sfd.ser”

Question

This is the error that I'm getting:

I goggled it a bit and I was told to change some policy for some file, but I'm totally lost on what to change.

Answer 1

I guess it's a serial number - did they change the license?

I wrote a pure java mp3 player: mp3transform - it is based on JLayer from JavaZoom when it was still LGPL.
