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

Show live progress of a long running task using af:progressIndicator in Oracle ADF

This post is about using af:progressIndicator to show live status of a particular task
af:progressIndicator state is tracked and maintained by it's value property that supports org.apache.myfaces.trinidad.model.BoundedRangeModel
This class has two methods

public abstract long getMaximum() { }

returns Maximum value for Model

public abstract long getValue() { }

returns value for Model (current state)

Now to see live progress on page we have to refresh progressIndicator component periodically and this can be achieved using af:poll component , poll component delivers poll events to server periodically and we can ppr (refresh) progress indicator after a particular interval
