In Jdeveloper 11.1.1.7 there is no option to create ADF Skin declaratively
In order to apply skin we have to create a simple CSS file and then configure application to use this CSS file as skin. Jdeveloper doesn't do this for us :( we have to do it manually
So first step is to enable Skin Selectors for ADF Faces, Without enabling this CSS editor doesn't show ADF Faces component tags
CSS files by default supports HTML tags only
Go to Tools > Preferences > CSS Editor and set CSS level to level 3 and check the box to support ADF Faces Components
