Pure Java was Sun's marketing catch phrase to promote programs/programming that required not other code than Java code (besides what was included with the standard Java Virtual Machine of course). > >Anyway, as per Wiki, the native library will still be >requred, right? Well, yes and no, as if you call the standard OS API libraries they are part of the operating system and thus are always there. So yes, of course you need native libs, but no, you do not need to distribute them or install them as they are part of the OS. JNA of course has some internal native code for each platform so it is a bit dishonest to say any solution based on JNA is Pure Java but it is so well maintained and cleverly implemented that all you need is a single jna.jar on your classpath to make it work, so it looks like Pure Java for the casual observer. > >Like this?

I think and hope that there is a way to use HID devices directly using the OS API on each platform, like IOKit in Mac OS X. > >Or this one? >https://github.com/BodyTrack/AirBot-Uploader/tree/master/java/lib/HIDAPI No, again this relies on native HIDAPI being present and the comments on that page clearly illustrate problem with this approach: "I don't have a Mac with OS X 10.5.x on it anymore, so I couldn't create the libhidapi32.dylib."
