Server Side Ajax
Duration:   2 Days
Audience Prerequisites

This course is designed for experienced Web application developers and professionals:

  • Architects
  • Designers
  • Consultants
  • Developers
  • Technical managers

Description
As Ajax-related technologies are being adopted rapidly by the Web development community, a new breed of Ajax frameworks have emerged - server-side Ajax component frameworks. They allow Ajax-kind of user experience delivered mostly by server-side components. Developers can use the server-side languages and tools they are mostly familiar with to develop, debug, and refactor these components.

This two day course looks at several such popular frameworks, including JSON-RPC for Java, DWR (Direct Web Remoting), GWT (Google Web Toolkit), Ajax4jsf, IBM's JSF Widget Library (JWL) and the tool support provided by Rational Application Developer (RAD) to build AJAX applications.
Objectives

This course aims to teach a set of advanced skills for implementing practical, industrial-strength Ajax solutions. On completion, attendees would be able to:

  • Understand what server-side Ajax frameworks are
  • What server-side Ajax frameworks are available
  • Use the JSON-RPC-Java framework to build and invoke server-side Java components
  • Use the DWR framework to allow Javascript in a browser to interact with Java on a server
  • Use Google Web Toolkit (GWT) to write the front end in Java and compile the Java classes to browser-compliant JavaScript and HTML
  • Use Ajax4jsf to add Ajax capabilities to JSF based Web applications
  • IBM's JSF Widget Library (JWL)
