There used to be a nice Java parallel port library available at this URL:

It seems to be gone now, however you can still access it through the Internet Archive's wayback machine:

The files can also be downloaded from here (Windows and Linux versions available, binaries and source code included):

Note that for Windows XP you'll need to install a kernel-mode driver such as UserPort. This also can be downloaded from the sites above.
