nxt - 无法加载 LeJOS NXT 通信驱动程序

我一直在尝试使用 LeJOS 库生成与我的 NXT 机器人的接口(interface)。当我运行代码时，我将以下错误打印到控制台:

我相信这与在 java eclipse: failed to load nxt usb comm driver 中发现的问题相同，并且我安装了 eclipse 32 位版本，但我仍然遇到同样的错误，即上面的错误。我将如何解决这个问题？

因为我的名誉不能发表评论(我是新人)，一个回答:
你应该确保你有:
- x86 JDK (Java开发工具包)，点击:jdk-7u21-windows-i586.exe
- 乐高迷影 drivers , 点击: Fantom Driver 1.1.3
正如您已经提到的 32 位版本的 Eclipse
