The rxtx libraries which should be part of the demo zip, are also
available in the jar 
linux	/lib/2.1.7/librxtxSerial.so
Windows	/lib/2.1.7/rxtxSerial.dll

Windows:
--------
The library must be some where in the PATH.

Linux:
------
For linux, it's somehow more complicated.
It's necessary to have it in 'LD_LIBRARY_PATH'
I'm not sure how to make this persistent, but
to use it locally do

export LD_LIBRARY_PATH=./

from you shell before launching 
java -jar libraries_demo.jar

---------------------------------------------------
The rxtx libraries we ship are 32bits only. 

So if you use a 64 bit jre, you'll have to provide 64bits libraries.
Such libraries are available at http://www.cloudhopper.com/opensource/rxtx/

We haven't done any test with them.
