What are JSR 168 and JSR 286?

JSR 168 and JSR 286 are Portlet Specifications They were created out of a need to have a specification for displaying

multiple applications on the same page.

The specs define the lifecycle of a portlet as well as itscharacteristics/look and feel.

They standardize the way portlets are developed.

What is a portlet?

A portlet is a web component that processes requests and generatesdynamic content.

The content generated by a portlet is also called a fragment (e.g.HTML, XHTML, WML) and can be aggregated with other fragments toform a complete document.

What is a portlet?

Portlets as fragments of an HTML page:


21/52


Portlet Lifecycle

Portlets are different from servlets in that they have a 2 phasecommit.

With servlets, the service() method processes all requests. With portlets, the processAction() method processes the requests

and the render() method draws the contents of the portlet on thepage.


22/52


Portlet Lifecycle

init() Initializes the Portlet

processAction() process input from a user action.

render() Renders the content output.

destroy() Cleans up the portlet

Portlet Characteristics

Portlets have additional characteristics that make them differentfrom Servlets

Portlet Modes Window States Portlet Preferences


26/52


Portlet Modes

Each portlet has a current mode, which indicates the functionthe portlet is performing.

All JSR 168 compliant portals should support the View, Edit andHelp modes.


27/52


Window States

Window states indicate the amount of portal page space thatwill be assigned to a portlet.

All spec compliant portals should support the minimized,maximized and normal window states.


28/52


Portlet Preferences

Portlets can be configured to provide a custom view or behaviorfor different users.

For example, a weather portlet can show the temperature inChicago for one user and the temperature in LA for anotheruser.

These configurations are represented as a persistent set ofname-value pairs and are referred to as portlet preferences.
