Swing: Look and Feel

I've found this page with a nice look and feel:

https://substance.dev.java.net/docs/skins.html#CremeSkin

But I can't use it.

I import this:

import org.jvnet.substance.skin.SubstanceCremeLookAndFeel;

And do this:

UIManager.setLookAndFeel(new SubstanceCremeLookAndFeel());

But the import-libary are not correct. Hope somebody can help me! I'm using netBeans.
