I am teaching two students who are bringing their laptops into class how to use Arduino, and we are trying to use the Serial library to communicate with Processing. Unfortunately, these two students get the following errors:


Code:
java.lang.UnsatisfiedLinkError: C:\Users\user\processing-1.2.1\libraries\serial\library\rxtxSerial.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform thrown while loading gnu.io.RXTXCommDriver

What can we do to fix this?
