Java Native Access - An essential tool in Java tool box

I recently learned about Java Native Access (JNA) and was simply amazed at how easy it is to make native calls. I have used JNI earlier in my projects to access native code, but it is a bit painful experience. JNA makes it a bit easier to make those native calls. I haven't experimented much with passing structures and getting structures (or pointers to structures) as return values. As far as the arguments and return types are one of the primitive types, the interface is very easy to define and use.

Give it a try, you will like it.
