1. Main features SSO (Singal Signon) single point landing Personalization Settings Personalization Permissions Management Content Aggation (Content Aggregation)
2. Composition portlet: portlet is a Java technology-based web component, which is managed by portlet container, responsible for processing requests and generating dynamic content. Portlets are used as a portal as an insertable user interface component, and the user interface component is used to provide a representation layer in the information system.
Portlet container: Portlet Container is used to manage the lifecycle of portlets and provide the necessary environments you need to run. And provide persistence (persistent) access services for Portlet Preferences. But it does not support the aggregation. AggRegation is provided by Portal components.
Note: Portlet Preferences is a new feature of Portlets, providing features similar to databases. But not for replacing the database. Just use to access the simple portlet parameter configuration.

5.JSR 168JSR 168 (Java portlet) is a Java specification that establishes a portable relationship between portlets and portals. One main goal of this specification is to establish a set of Java API standards for portals and portlet suppliers. These APIs involved include representation, aggregation, security, and portlet lifecycle.
