The thing is, this does NOT happen, if I wirte the Read-Method in a main function.
I have an appliation project and if I create a class with main method (in which I paste the read funktion of the tutorial) it's alright, if I change the methods name it doesn't. How can that be?
Do I have to specify some dependencies somewhere? To use jexel I just copied the required files into my Project and set the Buildpath accordingly.
