脱机运行Java Applet：线程“ main”中的异常java.lang.NoClassDefFoundError

Question

我刚刚从此站点下载了一些Java applet： http ： //www.surendranath.org/Apps.html ，可在笔记本电脑上离线运行它们。 以这个为例： http : //www.surendranath.org/Applets/Oscillations/Lissajous/Lissajous.html

通过检查源代码，我下载了文件： 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盒子上运行它

但是我收到以下错误消息：

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， 离线运行此applet的正确方法是什么？ 在我的浏览器中在线运行它，icetea插件可以运行。 但是我需要一种脱机运行它的方法。

编辑

尝试完全限定的类名会导致：

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

Answer 1

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/"
