![]() In JSF, all the components in a form are updated when that form is submitted. The UI components and bindings involved in authentication have nothing to do with the components and bindings involved in gathering feedback from the user, so these two groups of components should be organized into separate forms. A JSF view may contain several forms, and in general it is a good idea to divide your user interface into separate forms when it can accept different types of unrelated information from the user.Ī good example is a JSF view that has a page header with a user sign-in form, and a content area with a user feedback form. The tag component is very common in JSF views, as almost all components need to be included in a form in order to be functional. ![]() In JSF, we should always use the tag and not the actual HTML form tag to render a form because the JSF tag renders additional hidden form fields containing important information about the UI component tree for the current view. This produces an HTML form tag at request time. This tag renders a UIForm component as an HTML form using the default HTML RenderKit. To display a form on a JSF page, you can use the tag. At the end of the book, you will be introduced to the new and up-coming JSF component libraries that will provide a road map of the future JSF technologies. You will also learn how to solve the complex web application development challenges with the JBoss Seam framework. As you move through the book, you will learn how to build composite views using Facelets tags, implement common web development tasks using Tomahawk components, and add Ajax capabilities to your JSF user interface with ICEfaces components. This book progresses logically from an introduction to standard JSF HTML, and JSF Core components to advanced JSF UI development. ![]() JSF 1.2 Components is both an excellent starting point for new JSF developers, and a great reference and “how to” guide for experienced JSF professionals. This book provides a comprehensive introduction to the most popular JSF components available today and demonstrate step-by-step how to build increasingly sophisticated JSF user interfaces with standard JSF, Facelets, Apache Tomahawk/Trinidad, ICEfaces, JBoss Seam, JBoss RichFaces/Ajax4jsf, and JSF 2.0 components. It's the perfect way to build rich, interactive, and "Web 2.0-style" Java web apps. JavaServer Faces includes powerful, feature-rich, Ajax-enabled UI components that provide all the functionality needed to build web applications in a Web 2.0 world. Today's web developers need powerful tools to deliver richer, faster, and smoother web experiences.
