Jacob.jar cannot find jacob-1.18-x86.dll
提问by user3476534
I am trying to write Java code that uses autohotkey, specifically the autoitx4java implementation. I have the imports
import java.text.SimpleDateFormat;
import java.util.Date;
import autoitx4java.AutoItX;As well as have added Jacob.jar, AutoItX4Java.jar and sqljdbc4.jar in the build path (sql jdbc is for other parts of the code). It doesn't compile because of an unsatisfied link error:
我正在尝试编写使用 autohotkey 的 Java 代码，特别是 autoitx4java 实现。我有导入
import java.text.SimpleDateFormat;
import java.util.Date;
import autoitx4java.AutoItX;以及在构建路径中添加了 Jacob.jar、AutoItX4Java.jar 和 sqljdbc4.jar（sql jdbc 用于代码的其他部分）。由于不满意的链接错误，它无法编译：

I have the jacob-1.18-x86.dll in the system32 folder (windows 8.1 is the OS) as well as jacob-1.18-x64.dll and jacob-1.18-M3-x64.dll, just in case it wanted to use the 64 bit dll. I tried adding C:/Windows/System32 to the jacob.jar "Native library location" (using eclipse) from some website, but that didn't work. Some other site suggested putting the dll in the C:\Program Files\Java\jre7\bin folder, so I did that, but it still throws the error. This code used to work on a different machine, but now it won't compile because of the unsatisfied link. I can't figure out where to put the jacob-1.18-x86 to get it to find it.
我在 system32 文件夹中有 jacob-1.18-x86.dll（Windows 8.1 是操作系统）以及 jacob-1.18-x64.dll 和 jacob-1.18-M3-x64.dll，以防万一它想使用64 位 dll。我尝试从某个网站将 C:/Windows/System32 添加到 jacob.jar“本机库位置”（使用 eclipse），但这没有用。其他一些站点建议将 dll 放在 C:\Program Files\Java\jre7\bin 文件夹中，所以我这样做了，但它仍然抛出错误。这段代码曾经在不同的机器上工作，但现在由于不满意的链接而无法编译。我不知道把 jacob-1.18-x86 放在哪里才能找到它。

Well, copied it into the "C:\Program Files (x86)\Java\jre1.8.0_65\bin" folder and it worked. Apparently it only looks there for the jacob dll's.
好吧，将它复制到“C:\Program Files (x86)\Java\jre1.8.0_65\bin”文件夹中，它就可以工作了。显然它只在那里寻找 jacob dll。
