One more point.  Be sure rxtx 2.1 (RXTXcomm.jar) is not installed while 
trying to compile 2.0.  This is a very common mistake and results in 
problems not unlike what you are experiencing.  The 2.0 and 2.1 versions 
while nearly identical in native code use different java packages 
resulting in incompatability.  RXTX 2.1 can not be in the javax.comm 
namespace because of the (current) Sun license.
