To get started with cewolf -which is different from JFreeChart-, work through the tutorial at http://cewolf.sourceforge.net/new/. You'll also want to download the cewolf example web app, drop that in a servlet container, and check out its various pages and their respective JSP code.
Did you read through the tutorial? It's only 5 (short) pages.
Did you get the example web app to run? It includes the example chart from the tutorial so that you can play around with it yourself (as well as numerous other examples).
No, it's a JSP tag library. In AWT/Swing code you can use the JFreeChart API directly via the ChartFrame and ChartPanel classes. See http://faq.javaranch.com/java/JFreeChartDemo for an example.
