Web 2.0 portlet and portal programming
This article shows you how to exploit the benefits of the Web 2.0 tooling support in IBM® Rational® Application Developer V7.5 for portlet and portal applications running on IBM® WebSphere® Portal V6.1. In a typical portlet application, each request to the server causes a complete refresh of the browser page, which leads to page flickering and performance gaps. Web 2.0 technology enables you to create more dynamic and responsive applications with a superior user experience. The technology aims to turn Web browsers into semi-rich clients by projecting user interface logic for page rendering, navigation, aggregation, and cross-portlet interaction into user’s browsers.
The Web 2.0 tooling support provided with Rational Application Developer aids and expedites the process of creating such dynamic and responsive portlet and portal applications. Tooling support has been provided so that you can:
- Design portlets that interact using Client-Side Click-to-Action, which is a new event paradigm introduced in WebSphere Portal V6.1 for cooperation between portlets.
- Insert Person Menu and the capability to extend the Person Menu.
- Use an Ajax proxy for portlet applications.
- Use a client-side programming model to retrieve portlet preferences efficiently, performing portlet state changes on the client side.
