After discovering how to generate a Naked Object application in NetBeans with Maven I played with my freshly created project a little, as the way I suggested to start the application seemed to me quite slow.
After some investigation I managed to start the application in almost the same way I used to start the application built with Ant. Actually it's quite easy, once you get used to it. All you have to do is set the Run properties as follows:
The tricky part is that you have to set them for the Command Line project and not for the main one...
At this point, if you want to have an even faster start (by which I mean an easier one) you can set the Command Line project as main and then just press the F6 key.
