我嘗試在Applet上加載圖像或聲音時出現問題。我使用LWJGL applet和Slick2d加載圖像/聲音。 但是，當我啓動與Netbeans的小程序，有沒有問題...... 還有就是我用來加載聲音的代碼：使用LWJGL/Slick2d小程序加載圖像/聲音
public class Files {
public static Audio sound;
public static void load() {
try {
sound = AudioLoader.getAudio("WAV", ResourceLoader.getResourceAsStream("/snd/Tir1-16b.wav"));
} catch (IOException ex) {
Logger.getLogger(Files.class.getName()).log(Level.SEVERE, null, ex);
}
System.out.println("loaded with success !");
}
}
而且還有HTML頁面：
<applet code="org.lwjgl.util.applet.AppletLoader" archive="lwjgl_util_applet.jar" codebase="." width="800" height="600">
<!-- The following tags are mandatory -->
<!-- Name of Applet, will be used as name of directory it is saved in, and will uniquely identify it in cache -->

還有就是控制檯日誌顯示，當我啓動的HTML頁面的小程序：

空肯定意味着可變音頻爲空。這也意味着該文件可能沒有找到...所以我試圖把目錄「snd」和「sprites」放在applet目錄中，並且也放在我的applet的.jar上，但沒有任何反應......
任何人都可以幫我嗎？我搜索了很多時間嘗試在許多論壇上也發現這種問題，但沒有人幫助我...
非常感謝！
'NoClassDefFoundError'首先修復。什麼Jar是'ResourceLoader'位於？ –
