Today we will do JSF datatable pagination with a Lazy List with a view scoped managed bean. What all those words/expressions mean? There are several JSF frameworks today that provide datatables with a ready pagination, columns sorter and others functionalities. Today we will use the Primefaces datatable. Usually the datatables will put the displayed List, with the entities, inside the user http session. Increasing the objects inside the user session will have a direct impact on the server performance; each user that displays a datatable, that keeps a list in the session, will be allocating more and more memory in the server.
