如何使用JRuby创建Java applet？

I want to create a Java applet using JRuby. That is, I want to create a Java applet with Ruby code inside run by JRuby to do all the GUI stuff. I am looking for a simple example of how to do this to get started.

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.

对于您的情况,您可能拥有Java中的applet,引导一个org.jruby.embed.ScriptingContainer实例,然后将其提供给Applet实例,以便它可以在Ruby脚本中添加您的UI元素。 applet jar中的任何东西都可以直接加载,例如require'my_applet.rb'将在jar中查找/my_applet.rb。

Enjoy!
