JSF is now a well-known and widely accepted standard in the J2EE landscape. If you are still wondering what JSF is and how it can be used to build robust and easy to maintain applications for the web this presentation is for you. JSF is introduced with a discussion of what it is and how it works. You will understand why we have JSF as well as how it works. We also cover the architectural concepts behind how to build good JSF apps that are easy to understand and maintain. Next up we cover the Apache MyFaces implementation of JSF and some of the really cool extras you get from using MyFaces. These extras are fileupload, calendar, scrollable and editable table and custom validators, to name only some. Also there is built in support for Tiles, which allows you to compose web pages niftily. Another big plus is support for Cell Phones through its WML RenderKit. Best practices are discussed from a practical standpoint next. In other words we will answer the question ?what do I do to build a good JSF app??. We will also discuss how to connect your JSF application to back end services through both a POJO (plain old java object) interface using Spring?s IoC (Inversion of Control, AKA Dependency Injection) as well as interfacing with more traditional back end technology such as EJB?s. Finally we will go through an example with lots of code and a demo of some of the cool things you can do with JSF and MyFaces. In this session attendees will discover JSF and how to use it practically to build web applications.
