Portal Technology
► What
are Portals?
 Presentation Layer to
Info Systems
 Contains Portlets
► What
are Portlets?
 “Pluggable”
Components
 Modes
 States

Inter-Portlet Communication
► Types




of Portlets:
Portlets that do not communicate
Source Portlets
Target Portlets
Hybrid Portlets
Portlet A
message
Portlet B
Portal Server
action
update
WebUser
One Way Communication
‘Lookup’
Pressed
Sends Form Info.
Member ID
Portlet
(ActionListener)
Sends ID
Member Info
Portlet
(MessageListener)
Two Way Communication
Claim ID
Clicked
Sends Form Info.
Claim Search
Portlet
(ActionListener,
MessageListener)
Sends ID
Send New ID
Claim Info Portlet
(ActionListener,
MessageListener)
Sends Form Info.

Personalization
► Personalization
provides the ability to
restrict content displayed within portlets
► Types
 User Profile-Based
 Rules-Based
 Collaborative Filtering
► Used
to achieve Family of Portlets
Rules Personalization
► Classifiers
► Actions
► Binding
Customization
► Support
multiple user configurations
 Internet Explorer and Netscape, as well as
supporting localization issues
► Look
and Feel
 Themes and Skins
 Pages and Portlets
Themes
Skins
Single Sign-On (SSO)
► What
is SSO?
 SSO technology provides the capability for a
user to authenticate once while simultaneously
gaining access to multiple secure applications.
► WebSphere
Models of Authentication
 Web SSO
 Extended SSO
Web SSO
► Centralized
Authentication Model
 Once authenticated to the first application you
are authenticated to all
► Web
SSO allows a user to log-in to one
application, the application then generates a
token with the aid of some LTPA
authentication proxy.
Extended SSO
► User
Level Authentication
 Secrets stored at user level across Portlets
► System
Level Authentication
 Secrets shared across all users
► Setting
this up is a complex task that
involves possibly modifying the applications
which require SSO access.
Credential Vault
►
The Vault is broken into Vault Segments
 Vault Segments are broken into Vault Slots
 Vault Slots contain a Credential Object
LDAP
► Types
of Connection:
 Unsecured
 Secured (extension using SSL)
► Supports:
 IBM Directory Server, IBM Secure Way for IBM
Directory Server, iPlanet Directory Server, MS
Active Directory, Lotus Domino
► Other
LDAP directories can be used
Deliverables
► Primary
Deliverable
