推荐答案

来自Javadoc：

如果Java虚拟机无法找到声明为native的方法的相应本机语言定义，则抛出该函数。

Thrown if the Java Virtual Machine cannot find an appropriate native-language definition of a method declared native.

这是与JNI相关的错误。 loadJacobLibrary正在尝试加载名为jacob-1.14.3-x86的本机库，并且在java.library.path定义的路径上找不到它。启动JVM时，应将此路径定义为系统属性。例如。

It is an error related to JNI. loadJacobLibrary is trying to load the native library called jacob-1.14.3-x86 and it is not found on the path defined by java.library.path. This path should be defined as a system property when you start the JVM. e.g.

-Djava.library.path=<dir where jacob library is>

在Windows上，实际的本机库文件将被称为jacob-1.14.3-x86.dll而在Linux上，它将被称为libjacob-1.14.3-x86.so

On Windows, the actual native library file will be called jacob-1.14.3-x86.dll while on Linux it would be called libjacob-1.14.3-x86.so
