Java Native Access

Java Native Access (JNA) is an alternative to Java Native Interface (JNI) that does not require writing C/C++ wrapper code – it basically allows a ffi style calling ability for C functions contained in dlls.

I had long had the view that it was unfortunate that it was so hard to directly interface Java with lower level code. This seems like for simple cases it makes this much simpler, and for hard cases, there is JNI.
