脫機運行Java Applet：線程“ main”中的異常java.lang.NoClassDefFoundError

Question

我剛剛從此站點下載了一些Java applet： http ： //www.surendranath.org/Apps.html ，可在筆記本電腦上離線運行它們。 以這個為例： http : //www.surendranath.org/Applets/Oscillations/Lissajous/Lissajous.html

通過檢查源代碼，我下載了文件： wget http://www.surendranath.org/Applets/Oscillations/Lissajous/LissajousApplet.class

然后我嘗試通過gappletviewer-4.8 -code LissayousApplet.class在我的Ubuntu盒子上運行它

但是我收到以下錯誤消息：

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， 離線運行此applet的正確方法是什么？ 在我的瀏覽器中在線運行它，icetea插件可以運行。 但是我需要一種脫機運行它的方法。

編輯

嘗試完全限定的類名會導致：

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

嘗試使用完全限定的類名

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