Greetings!

I’ve just started with jMonkeyEngine a few days ago. Right now I’m trying to understand how nodes work in jME following a few tutorials, but for some reason my code doesn’t work when I create a new node.

When I add these two lines at the end of my simpleInitApp() method, it gives me an error:

```
Node pivot = new Node("pivot");
rootNode.attachChild(pivot);
```

Also I have tried:

```
pivot = new Node("pivot");
rootNode.attachChild(pivot);
```

and:

```
Node pivot = new Node("pivot node");
rootNode.attachChild(pivot);
```

I’m running jME on a Debian Wheezy.

Does anybody know what am I doing wrong?

Thanks!!!
