If you are interested in how someone has implemented it, check out http://williamjturkel.net/2011/12/25/connecting-arduino-to-mathematica-on-mac-os-x-with-serialio/  I will try it out on my own soon and will report back if it worked. Have you had any luck?

I have not played with javax.comm, but in general you should do

Needs["JLink`"]

then use AddToClassPath to make Mathematica scan the extra library.

If this works, it should change the error message (!!), but you will 
still need to get the dll in the correct place. If you are working in 64 
bits (I don't think this was mentioned) you will need a 64-bit version 
of the library. Placing it somewhere on the PATH (type PATH in a command 
box to see this) should work.
