JNA provides Java programs easy access to native shared libraries (e.g. DLLs on Windows) without writing anything but Java code—no JNI or native code is required. This functionality is comparable to Windows' Platform/Invoke and Python's ctypes. Access is dynamic at runtime without code generation.
JNA's design aims to provide native access in a natural way with a minimum of effort. No boilerplate or generated code is required. While some attention is paid to performance, correctness and ease of use take priority.

J/Invoke - http://www.jinvoke.com - is a similar commercial product that also lets you do this. It makes calling functions from a native DLL as easy as P/Invoke does for .NET. Java developers can simply annotate a native method with the DLL and function name and J/Invoke manages the task of loading the specified DLL, automatically converting Java arguments to C arguments and invoking the target function in the DLL.
