Hi Vic,
Sorry for the delay. I've had a busy and maddening week.

We're still coming to grips with NetBeans. At first we thought you wanted
some special classes to work with NetBeans that were like JavaBeans, but I'm
starting to think you just want iCommand to work in an IDE called NetBeans?

That was version 0.5, released October 30:

It's best to use the code samples in the samples directory rather than
trying to interact with the low-level NXTComm class. The sample code shows
the common ways to use iCommand.
That aside, I can see from the output that the environment variable NXTCOMM
is not set to the COM port your Macintosh is using for serial Bluetooth. The
readme file has some important information on this in section 2.2.2. I'm not
very happy with the organization of the readme but it's all we have at the
moment.
