THE SETTING
S. Pérez & O. Díaz

Portal, Portlet & Portlet Container
“A portal is a web application whose main focus is
on integration and personalization”
“A portlet is a Java technology based web
component, managed by a portlet container”
“A portlet container runs portlets and provides them
with the required runtime environment.”
S. Pérez & O. Díaz

Portlets as commercial-off-the-shelf
(COTS) Web components
 The very same portlet can be re-used in
different portals
 Adaptation is a must to customize the
portlet to the portal setting
 Mashup as a customization technique for
portlets into portals

Sample scenario: “Mashuped portlet”
When THIS portlet is offered through THIS portal then…
add weather widget

CHALLENGES
S. Pérez & O. Díaz
11
Challenge 1: Composition
 So far, portlets & widgets are co-located
 Portals should permit portlets to inlay mashup content
(e.g. widgets)
Location &
Date
S. Pérez & O. Díaz
Challenge 2: Orchestration
 Not
just
integration
visual
 Operational
integration
• Parameter passing
 Enhanced
experience

Portlet mashuping: three dimensions

REALIZATION

15
“Where” dimension

16
“Where” dimension: the issue
S. Pérez & O. Díaz
17
“Where” dimension: realization
 Portlets return markup fragments to be
rendered by the portal
 This markup now holds placeholders
 Augmented mashup is restricted to these
placeholders

(What, Where) coordinate
 Insert WeatherForecastGadget into topmashcell
S. Pérez & O. Díaz
20
(What, Where) coordinate: realization
 XML Binding Language (XBL) permits to
describe bindings to elements in other
documents
• binding: XBL document
• bound element: specificied through a CSS
 It is a W3C candidate recomendation
S. Pérez & O. Díaz
21
(What, Where) coordinate as an XBL
 Bound element: top-mashcell of portlet markup
 Binding: WeatherForecastGadget
S. Pérez & O. Díaz

23
WHAT
(How, Where) coordinate
 Obtain city parameter of gadget from
“destination” entry at the portlet
S. Pérez & O. Díaz
(How, Where) coordinate as an XBL
 Bound element: destination node
 Binding: handler for destination propagation

CONCLUSIONS
S. Pérez & O. Díaz
27
Conclusions
 This work introduces a mashup-like approach to
personalization in portals
 Once the portal is deployed, users can supplement portal
services with their own widgets that easy the fulfillment of
portlet services
 Implemented for Liferay using XBL
