Java Applet 在 Netbeans 中运行，但不会在浏览器中运行

Question

我用 Netbeans 创建了一个 Java 小程序。它是一个 GUI 横幅创建器。它在 Netbeans applet 查看器中运行良好，但当我使用 HTML 加载它时，出现错误。它正在查找类文件，但随后我得到：

我已经阅读了一些需要右键单击我的项目然后转到库的地方。一旦我到达那里，我就安装了 Beans Binding Library。还有其他地方安装了 beans.jar 文件（我有）。

如何解决这个运行时异常？

Caused by: java.lang.NoClassDefFoundError: org/jdesktop/beansbinding/Property

将包含 org.jdesktop.beansbinding.Property 类的 Jar 添加到 applet 元素的 archive 属性。
