Seam and Ajax4JSF are not covered in the book since they are not part of the
Java EE 5 specification, they are additional libraries and frameworks that build on top of it.
The book does cover the Woodstock
JSF component library, since NetBeans has outstanding support for it out of the box via the Visual Web JSF tool.
My other book, "Java EE 5 Development Using GlassFish Application Server" has brief coverage of both Seam and Ajax4JSF.
