Welcome to the JavaServer Faces FAQ! This FAQ answers questions about what JavaServer Faces is, how it works, and how it fits into the overall Java web development landscape.

This FAQ was derived from JavaServer Faces in Action. The book has more complete and colorful answers to these questions, as well as a bunch of other useful information you'll need for building JSF applications and components.

If you find any errors or omissions, please let us know.

Please note that all ASP.NET comparisons are based on the .NET Framework 1.0.
