Yes; you need to use native methods. How you go about doing it depends
on which version of the JDK you're using (the techniques are quite
different with JDK 1.1 vs. JDK 1.02) and whose VM (the Microsoft VM
and Sun VM support different native method interfaces).

If you want to learn how to do it with JDK 1.1 and the Sun VM, visit
the Sun web site and get a copy of the Java Native Interface
specification. If you want to learn how to do it with the Microsoft
VM, visit the Microsoft web site and look for a document whose name I
don't recall right now (the information is in MSDN, too, I believe).
If you want to do it with JDK 1.02, I suggest you rethink it. :)
