Java代码可以在windows上运行，但不能在linux上运行

Question

我有这段代码，我试图在 Windows 上运行一些代码，它运行良好，因为我得到了所需的输出

    }
}

在 Linux 上运行时，出现以下错误。

Exception in thread "main" java.lang.NoClassDefFoundError: com/jacob/activeX/ActiveXComponent

为了编译这个，我使用下面的命令

 javac -cp  jacob.jar ExpressionTransformerImpl.java

为了运行这个，我使用这个命令

java ExpressionTransformerImpl

如何解决这个问题？

任何帮助将不胜感激。

你运气不好。 JACOB 需要一个仅适用于 Windows 的 jacob.dll 文件。
