Question

Lesson 2 - when running the first GPIOLEDtest.java I received the following error:
[ERROR] [DAAPI] iso=-1:There is unexpected error, when open GPIO pin 23
startApp: IOException: java.io.IOException
Uncaught exception: java.lang.NullPointerException

Thanks Tom,
No, not running - I now run the TestIMLetListener and it does not compile either throwing:
Building jar: D:\MeineDaten2014\8-IoT\MOOC-Java8ME-Sessions\Lesson1\TestIMletListener\dist\TestIMletListener.jar
D:\MeineDaten2014\8-IoT\MOOC-Java8ME-Sessions\Lesson1\TestIMletListener\nbproject\build-impl.xml:468: Problem: failed to create task or type nb-copyliblets
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.

Is there any substantial lib or java functionality missing ? do I have to hook/check more "optional packages" under Netbeans 8.0/properties/platform ?
My Raspi OS is: Linux raspberrypi 3.10.33+ #1 PREEMPT
I will re-install the OS for new...(2014-01-07-wheezy-raspbian) and keep this updated...
