提问by somesh
I use to load the dll library in java program it . show the error. like this Directory separator should not appear in library name:.
我用来在java程序中加载dll库。显示错误。像这样 目录分隔符不应出现在库名中：。

suppose i use the only system.load()it may show one type error . that is
假设我只使用system.load()它可能会显示一种类型的错误。那是
Expecting an absolute path of the library: Macintosh HD/Users/sakkisetty/Documents/dll/FasExtend.dll
and use the full name system.loadlibrary(). it may show another type error. that is
并使用全名system.loadlibrary()。它可能会显示另一种类型的错误。那是
Exception in thread "main" java.lang.UnsatisfiedLinkError:
Directory separator should not appear in library name:
Macintosh HD/Users/sakkisetty/Documents/dll/FasExtend.dll
so i am using mac OS. please tell me solution for this problem.
所以我使用的是 mac 操作系统。请告诉我这个问题的解决方案。

System.loadLibrary only accepts a filename and looks for the file in the current java paths available. You'll want to add the directory containing FasExtend.dll to your java path, then just use
System.loadLibrary 只接受文件名并在当前可用的 java 路径中查找文件。您需要将包含 FasExtend.dll 的目录添加到您的 java 路径中，然后只需使用
System.loadLibrary("FasExtend")
