About Pagelets/Portlets and the Gateway
All pagelets/portlets are designed to be displayed with
other pagelets/portlets. Oracle WebCenter Interaction and Oracle WebCenter
Ensemble both act as a gateway, processing and combining pagelets/portlets
from multiple applications to create a single, unified page with a
range of functionality.
The code returned by a pagelet/portlet is parsed by the gateway
server and inserted into the appropriate cell in the HTML table that
makes up the mashup page. Pagelets/portlets from the same back-end
application can interact with each other within the page.
The same pagelets/portlets can be used in both Oracle WebCenter Interaction and Oracle WebCenter Ensemble, but a different
process is used to implement the mashup page.
- Modeled after the “window”
metaphor from desktop user interfaces, Oracle WebCenter Interaction
displays portlets as a series of windows or boxes arranged in columns
on a page with borders, title bars, buttons, headers and footers rendered
by the portal framework. The page layout is defined through the portal's
administrative UI. Each My Page or community page is made up of many
portlets, selected and arranged using portal editors. (Portlets are
pagelets specifically designed for use in Oracle WebCenter Interaction.)
- In Oracle WebCenter Ensemble,
a consumer page defines the layout and includes specific pagelets
in the page using adaptive tags. The portal header is not included
by default, but portal header navigation can be added using tags.
