As the one web framework that’s actually a Sun specification, Java developers cannot simply ignore JSF. With new frameworks like Seam based upon its foundations, it’s clear that JSF has much to offer. Though it’s taken some time for JSF to take off, with the availability of books like Pro JSF and Ajax by John R. Fallows and Jonas Jacobi (Apress, 2006), it is clear that the momentum is there. Using existing components and leveraging integrated tools can slash implementation time and allow developers to focus on the business needs instead of the plumbing of a web application. While we’ve only scratched the surface of what can be done in JSF and Ajax, hopefully we’ve given you the tools to try it out for yourself.
