JSF Training with Custom Components and Ajax (5 days)

JavaServer Faces Course Overview

Then, we change our perspective a bit and start thinking in terms of reusable component libraries -- using them and also developing them. Custom components prove to be the ideal delivery vehicle for JavaScript in JSF applications, and ultimately serve as the backbone of a robust Java/Ajax architecture. We work with two popular component libraries along the way -- Tomahawk and RichFaces -- and also get a look at Direct Web Remoting, or DWR.

A bridge module is also available that illustrates how JSF can work with EJBs and Java Persistence API entities; this brief presentation makes for a nice side trip during class time, for student groups who know they'll be working with JPA or EJB.

JavaServer Faces Course Goals

• Understand the purpose and scope of the JSF architecture
• Build Web applications using JSF's FacesServlet, faces-config.xml, and the JSF request/response lifecycle
• Use managed beans to encapsulate not only server-side form handling but also client-side presentation logic
• Implement control logic as JSF event listeners or action methods.
• Use validators and converters to implement a validation phase for a JSF application
• Use custom component libraries.
• Develop custom components for a variety of purposes, including composite components.
• Use custom components to encapsulate and deliver JavaScript content.
• Develop Ajax applications using JSF and DWR.
• Develop Ajax applications using RichFaces.

JavaServer Faces Course Prerequisites

Experience in the following areas is required:

• This course is intended primarily for experienced Java application developers. Page authors, component developers, and others who may have little or no Java experience (but perhaps are stronger on HTML and JSP) may well find this to be a valuable training experience, though without solid Java skills many of the coding exercises will be difficult to follow.
• Java programming experience is essential to understanding the JSF API as presented here
• JSP page-authoring experience is required
• Servlets programming experience is recommended but not required
• Basic knowledge of XML will be helpful, as will any previous experience with HTML.
