Not exactly Arduino news, but hopefully still relevant.. I have released a Java XBee API on Google Code GitHub - andrewrapp/xbee-api: Java library for communicating with XBee radios
It supports both Series 1 and Series 2 XBee radios, configured in API mode (AP=2). Since it's written in Java, it runs on a variety of platforms (Win/Mac/Linux) and there are even a few different language options: Python (Jython), Ruby (JRuby) etc.
interesting, and thank you for the news and the link to the project.
It just beeps when i run the executable? I don't know about Java. what am i doing wrong?

What is the basic difference between using API mode and AT mode?
API gives you more features, usually helpful if you project is pretty complex or you expect lots of debug stuff. If you just want to pass serial from point a to point b, you should use AT.
