Java Programming

Hello:

I�m making a little program that have to use serial port to comunicate with a device but I have to use it in Windows. I have downloaded the java communication API from the download center but i still haven�t found a windows version. There are versions for solaris linux and generic but in the generic distribution there isn�t a "win32com.dll" . In all the tutorial I have found say that I need the file. (here is a tutorial example http://dn.codegear.com/article/31915 )

I wonder where can I get a windows distribution and if a package of the Java Communications API version 3.0 for windows is avaiable. If this isn�t so. what can I use to comunicate with the serial port in windows using java?

Thanks, beforehand.
