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 its characteristics/look and feel.
• They standardize the way portlets are developed.

What is a portlet?

• A portlet is a web component that processes requests and generates dynamic content.
• The content generated by a portlet is also called a fragment (e.g. HTML, XHTML, WML) and can be aggregated with other fragments to form a complete document.
• Portlets as fragments of an HTML page:

Portlet Lifecycle

• Portlets are different from servlets in that they have a 2 phase commit.
• 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 the page.

Methods()

• init() – Initializes the Portlet.
• processAction() – process input from a user action.
• render() – Renders the content output.
• destroy() – Cleans up the portlet
• serveResource() – Allows a portlet to serve a resource.The serveResource() method can be used to implement AJAX use cases.
• processEvent() – Perform events triggered by other portlets. (IPC)

Liferay Implementation

• Portal RequestLifecycle (1)  -PortalRequestProcessor
• Portlet RequestLifecycle (x)  - PortletRequestProcessor

These extend TilesRequestProcessor in Struts!

Portlet Characteristics

Portlets have additional characteristics that make them different from Servlets

• Portlet Modes
• Window States
• Portlet Preferences

Portlet Modes

• Each portlet has a current mode, which indicates the function the portlet is performing.
• All JSR 168 compliant portals should support the View, Edit and Help modes.

Window States

• Window states indicate the amount of portal page space that will be assigned to a portlet.
• All spec compliant portals should support the minimized, maximized and normal window states.

Portlet Preferences

• Portlets can be configured to provide a custom view or behavior for different users.
• For example, a weather portlet can show the temperature in Chicago for one user and the temperature in LA for another user.
• These configurations are represented as a persistent set of name-value pairs and are referred to as portlet preferences.

Portlet Development Strategy

• Overview recommended best practices for developing portlets and extending Liferay Portal’s functionality.
• Understand the compromises involved in each of the methods.
• Evaluate how to combine the different methods for the needs of your organization.
