这个是我播放音乐的类.
if(e.getSource()==onMusic&&musicFlag){
//String path = getClass().getProtectionDomain().getCodeSource().getLocation().getPath()+"/com/mouse/sounds/background.mp3";
File file = null;
try {
file = new File(getClass().getResource("sounds/background.mp3").toURI());
} catch (URISyntaxException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
//File file=new File(path);
mp3=new Mp3Player(file,true);
// getClass().getResource("sounds/background.mp3").;
musicFlag=false;
}
在MYECLIPSE里运行没错误,但是一打JAR包音乐就会出错,求高人帮助呀
------解决方案--------------------------------------------------------
路径的写法好像没错吧，是不是你打完jar包后，确保sounds的文件夹和jre的文件夹 都拷贝出来了，sounds不要放在src的文件夹下（我说的是放在一个没有jdk环境的电脑上的），可以参考一下
------解决方案--------------------------------------------------------
手动打jar包比较保险一些 用程序打包一般都会出错的
------解决方案--------------------------------------------------------
要连同第三方jar一起打入jar包的
