Question

我正在尝试在Netbeans 7.0.1中加载DLL文件，

代码是

dll = (RRHFEK02DLL)Native.loadLibrary("RRHFEK02DLL.dll", RRHFEK02DLL.class);
utility = (Utilities)Native.loadLibrary("Utilities.dll",Utilities.class);
wraper =(RRHFEK02Wrapper)Native.loadLibrary("RRHFEK02Wrapper.dll", RRHFEK02Wrapper.class);

第一行没有错误，这行是在提供者的演示中，现在我想要另外两个dll加载，我已经添加了下两行并且还在库中添加了dll文件，但是我收到了错误

我已经通过相同/相关的问题传出，但没有得到解决方案。所以，如果有人提出建议，请提供给我。

Answer 1

您需要插入.dll扩展名（如果扩展程序为.framework，则在Mac上不需要。在我的系统上，使用我的netbeans项目文件夹结构：

LIB

+ src
+ EDSDK
      -dll
          -EDSDK
      -headers
+Other Files

做：

this.EDSDK = (EdSdkLibrary) Native.loadLibrary("EDSDK/dll/EDSDK.dll", EdSdkLibrary.class

有效加载它。在加载之前，您可以尝试new File("RRHFEK02DLL.dll").exists()返回的内容。如果false，那么您的路径是错误的。如果是true，那么问题就是

删除Java中的".dll"。那就是：

dll = (RRHFEK02DLL) Native.loadLibrary("RRHFEK02DLL", RRHFEK02DLL.class);
utility = (Utilities) Native.loadLibrary("Utilities", Utilities.class);
wraper = (RRHFEK02Wrapper) Native.loadLibrary("RRHFEK02Wrapper", RRHFEK02Wrapper.class);

请勿修改实际的DLL文件名称！
