我正在尝试运行 JNI 以在 W7 X64 机器上调用内置于 VS 2010 Express 的 DLL，但我总是收到上述错误。（注意：DLLTestProject.java/.class 在 dlltestproject 包下
源代码 ：
/*

package dlltestproject;
/**

public class DLLTestProject {
/**

static{
System.loadLibrary("NewDLLTest");
}
public static void main(String[] args) {
System.out.println(System.getProperty("java.home"));
DLLTestProject t = new DLLTestProject();
t.inDll();
}
public native void inDll();
}
