Class JetspeedWebPageService

java.lang.Object
  org.apache.jetspeed.services.webpage.JetspeedWebPageService

All Implemented Interfaces:

org.apache.jetspeed.services.webpage.WebPageService

public class JetspeedWebPageService

extends java.lang.Object

implements org.apache.jetspeed.services.webpage.WebPageService

This is the default implementation of the WebPageService interface.

It is a service that provides Web Page facade and delegation services for clients to transparently access resources existing on web pages from requests originating from the portal server.

Since the WebPage service is giving the appearance of a single session to the client, the service needs to manage the synchronization of sessions, including single-sign-on, and security authorization permissions between the the portal server and one or more sites.
