Presentations

Filthy Rich Portlets with ICEfaces and Liferay

When a portlet form is submitted, all the other portlets on the same
portal page are forced to redraw themselves. Learn how ICEfaces
Direct-to-DOM rendering provides a cure for this disruptive end-user
experience, and how ICEfaces Ajax Push supplies a rich alternative for
inter-portlet communication. Demonstrations will be performed within
Liferay Portal, a JSR 286 (Portlet 2.0) compliant portlet container.
- Portal Technology Overview
- Explain the advantages of portal technology
- Describe what portlets are and how Liferay is an open source portlet container
- Explain the advantages of using a framework like JSF for portlet development
- JSR 127 and JSR 168 designed to work together
- List of new features in JSR 286
- Describe the new Ajax-related features of the JSR 286 spec and what it means for rich portlets

- Demo#1: Typical JSF Portlet
- Submitting a form causes an HTTP POST and a subsequent redirect that causes the browser to re-render the entire page
- Other portlets on the page are forced to re-render themselves

- ICEfaces Technology Overview
- Describe how ICEfaces makes use of Ajax in order to extend the JSF standard
- Explain the ICEfaces Direct-to-DOM (D2D) technology
- Explain the idea of partial-submit and why it is an essential feature of JSF 2.0
- List some of the rich user interface components provided by ICEfaces

- Demo#2: ICEfaces Portlet
- Partial submit provides client-side field validation for free
- Submitting a form causes incremental page updates, rather then re-rendering the entire page
- Other portlets on the page are not disturbed

- ICEfaces Extended Request Scope
- Describe how the ICEfaces extended request scope is the perfect match for the lifespan of a portlet

- Using ICEfaces Ajax-Push for Inter-Portlet Communication
- Describe how ICEfaces server-initiated rendering can be used to perform inter-portlet communication between portlets on the same page and/or between portlets in different user sessions

- Demo#3: Sample Portlets Built with ICEfaces
- Ajax Push Inter-Portlet Communication
- File upload with Ajax Push progress indicator
