我想知道是否有人可以帮助我解决这个问题，因为我一直在努力让它发挥作用。
有一个现有的 Java 小程序肯定可以工作，但我需要将它从目录层次结构顶部的当前位置移动到它内部深处的某个位置。
运行它的原始 HTML 代码是这样的：
<html>
<applet code=DSVisApp.class
archive="jcommon-1.0.16.jar,jfreechart-1.0.13.jar,
jung-graph-impl-2.0.1.jar, jung-visualization-2.0.1.jar,
gson-1.7.1.jar, jung-algorithms-2.0.1.jar, jung-api-2.0.1.jar,
collections-generic-4.01.jar,colt-1.2.0.jar" name=DSVis height=100%
width=100%>
</applet>
</html>
（我知道，我刚刚继承了它。我想让它从新位置开始工作，然后担心切换到<object>。）
结构是：
DSVisApp
+ bin
+ + DSVisApp.class
+ + and lots of other classes for this applet
+ src
+ a couple of other directories
jcommon-1.0.16.jar
and all the other jar files with support code
这适用于上面的 HTML。
现在我想把它放在几个目录级别，例如：
alpha
+ beta
+ + gamma
+ + + delta
+ + + + DSVisApp...
+ + + + jar files...
我以为我可以只输入一个 codebase="/alpha/beta/gamma/delta" 但如果我这样做，我会得到：

反正我的头发不多——把它撕下来很痛。
它可能是服务器或 Java 配置的东西吗？因为很明显原始版本没有指向实际的类——实际的类在 DSVisApp/bin/DSVisApp.class）
