脱机运行java applet :线程"main“java.lang.NoClassDefFoundError中的异常

Question

我刚刚从这个站点下载了一些java小程序：http://www.surendranath.org/Apps.html，以便在我的笔记本上脱机运行它们。以这个为例：http://www.surendranath.org/Applets/Oscillations/Lissajous/Lissajous.html

通过检查我下载的源代码：wget http://www.surendranath.org/Applets/Oscillations/Lissajous/LissajousApplet.class

然后我尝试通过gappletviewer-4.8 -code LissayousApplet.class在我的ubuntu盒上运行它。

但是，我收到了以下错误消息：

Exception in thfully qualifiedread "main" java.lang.NoClassDefFoundError: loaded class LissajousApplet was in fact named Applets.Oscillations.Lissajous.LissajousApplet
   at java.lang.VMClassLoader.defineClass(libgcj.so.14)

   at gnu.classpath.tools.appletviewer.StandaloneAppletViewer.<init>(libgcj-tools.so.14)
   at gnu.classpath.tools.appletviewer.Main.main(libgcj-tools.so.14)

那么，运行这个applet 脱机的正确方法是什么呢？在我的浏览器和冰箱插件中在线运行它。不过，我需要一种脱机运行它的方法。

编辑

尝试完全限定的类名将得到以下结果：

gappletviewer-4.8 -code Applets.Oscillations.Lissajous.LissajousApplet.class -codebase codebase="../../../"

尝试使用完全限定的类名

gappletviewer-4.8 -code Applets.Oscillations.Lissajous.LissajousApplet.class -codebase codebase="http://www.surendranath.org/"
