This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
Primefaces seems good, I tried using JFreeCharts with Richfaces a year back and had a tough time. If a JSF library like Primfaces gives you out of box charting functionality, that is the right way ahead. Thanks Robert I will give it a look too.
I am suprised Richfaces has not caught up on Charting yet.
