If you're using JNA, feel free to tell us about it. JNA is a mature library with dozens of contributors and hundreds of commercial and non-commercial projects that use it. In addition, JNA includes a platform library with many native functions already mapped as well as a set of utility interfaces that simplify native access. While significant attention has been paid to performance, correctness and ease of use take priority. This makes it quite easy to take advantage of native platform features without incurring the high overhead of configuring and building JNI code for multiple platforms. The developer uses a Java interface to describe functions and structures in the target native library. JNA uses a small JNI library stub to dynamically invoke native code. Most calls require no special handling or configuration no boilerplate or generated code is required. The Java call looks just like the call does in native code.

JNA allows you to call directly into native functions using natural Java method invocation. This functionality is comparable to Windows' Platform/Invoke and Python's ctypes. JNA provides Java programs easy access to native shared libraries without writing anything but Java code - no JNI or native code is required. Questions, comments, or exploratory conversations should begin on the mailing list, although you may find it easier to find answers to already-solved problems on StackOverflow. The definitive JNA reference (including an overview and usage details) is in the JavaDoc.
