有关你的情况，你可能已经用Java小程序，自举一个org.jruby.embed.ScriptingContainer实例，然后给它的小程序实例，以便它可以在一个Ruby脚本添加您的UI元素。任何在applet的jar可以直接加载，例如需要'my_applet.rb'将查找在罐子/my_applet.rb。

For your case, you'd probably have the applet in Java, bootstrap an org.jruby.embed.ScriptingContainer instance, and then feed it the Applet instance so it can add your UI elements in a Ruby script. Anything in the applet jar can be loaded directly, e.g. require 'my_applet.rb' will look for /my_applet.rb in the jar.
