Reading the serial usb data

I want to write an app that simply reads the serial data over the USB.
Now I want to write this in JAVA.

I have read about javax.usb , jusb and more stuff but I can't understand how it can be done. obviously it can be done.

How?
and if you do not know how. Do you know how with another programming language?

With kind regards Machiel

have you got any tips about this this?

Oh yeah, I have OSX....

RXTX and OSX work together. You just have really weird Com Port names compared to what I know about... Linux and Windows. I can't actually help you with OSX though.
