Configure ADF Skin in Jdeveloper 11.1.1.7

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

Drag Drop in same table to reorder rows, Update Attribute value to make it persistent

This post is based on Frank's article on reordering table rows using drag drop functionality of ADF Faces, post uses iterator indexing to change order of rows and it works pretty good

Recently i came across a question on OTN forum asking about making this ordering persistent on base of some attribute value so for that we have to maintain a serial no attribute for each row and when user performs Drag n Drop , serial no. will be swapped and updated ordering of rows will be shown to user and it is persistent as updated attribute's value is saved in database
