using chameleon-blue theme

gentlemen, good evening. I’m rewriting using Vaadin, an application made ​​with GWT-Ext. I would use the chameleon-blue theme. I’ve tried a lot and could not. Can someone help me set up this theme in my application?
Thank you.
a hug

Continuing … I use Vaadin 7.1.6 and Eclipse. Could anyone help me to use the theme chameleon-blue in my application?

OK, Lukasz, thanks for the help. Finally managed to make the theme work.
