• The canonical answer is JNI. However, this is somewhat painful. Other options:

  • Swig
  • JNA
  • NativeCall
  CDR : If you also add which one is the latest and best that would have been helpful too. Like initialy it was JNI. Then someone wrote a better solution Swig. Then finding Swig's limitation some wrote JNA which is double faster than Swig etc

  Jon Skeet : Unfortunately I don't know that history.
