XbeeSeries 2 and Javelin Stamp

hello everyone:
does anyone have any exprience with the Javelin Stamp hardware confuguration and the Xbee series 2, I found a code on my yahoo groups, and I been told that it works, but for some reason I can’t get any communications between the two, I think is the hardware connection does anyone could help me with the hardware configuration, I’m doing everything in a regular breadboard and I created my own breakout board.

I’m attaching the library as well as the code

so far all I have in my breadboard is the 3.3V regulator, the connection between the javelin and the xbee series 2 is direct TX to TX and RX to RX nothing else… do I need anything else?
