Introduction

Based on the Sun portlet specification JSR-168, a portlet is a Java-based web component, managed by a portlet container, that processes requests and generates dynamic content. Portlets are used by portals as pluggable user interface components that provide a presentation layer to Information Systems.

WDK for Portlets installs Documentum portlets, WDK run time, and WDK components into a portal Web application in a certified portal server. A single portlet class, DocumentumComponent, dispatches WDK components for each portlet. A portlet that dispatches a WDK component must specify its portlet class as com.documentum.web.env.jsr168.DocumentumComponent.

The components that are dispatched for portlet view and edit modes are specified for each portlet in the portlet.xml file. The context-sensitive portlet help file is dispatched to a new browser window based on the value of the help mode in the portlet.xml file.

If your IDE creates portlets by creating the portlet class, make sure you do not create a Documentum portlet specifying the portlet class as DocumentumComponent. The IDE will overwrite the Documentum portlet class and render all Documentum portlets invalid. If this happens, you can restore the portlet class from your installation WAR file.
