To enable interoperability between Portlets and Portals, this specification will define a set of APIs for Portal computing addressing the areas of aggregation. The Java platform provides an standard referred to as JSR that standarizes how portlets interact with portlet containers and ensures compatibility across. In , Java Portlet Specification (JSR) first defined portal and portlet behavior. In , Java Portlet Specification (JSR) refined and built on.

The Expert group will consider functionality such as portelt for, parallel execution of Portlets within a single user request, logging, security and personalization. Do you give us your consent to do so for your previous and future visits? Different implementations are available today, the following list enumerates some of them: Follow learning paths and assess your new skills.

A JSR portlets catalog makes sure that portlets under this catalog may run on any standards—compliant Java portal server. Even so, the advantages of modularity porglet so great that we still recommend you develop your portlets as OSGi modules. The Portlet specification will define the different components for Portal Computing, their interaction, lifecycle and semantics.

Initially Java portal vendors had their own portlet development framework thus those portlets were confined to specific portal servers and couldn’t be deployed to the rest of the Java portals. McDaniel Get fluent in a variety of features for your specificationn, scalable, and fault-tolerant cloud….

From Wikipedia, the free encyclopedia. Portlet filters are similar to servlet filters in that they allow request and response modification on the fly. Client agnostic Support for multiple types of clients multi-device Simple Portlet API Support for Localization and Internationalization Hot spwcification and re-deployment of Portal applications Declarative security same as to the mechanism found in Servlet and EJB specs Architected to support remote execution of Portlets The Portlet specification will be based on the Servlet specification.


Portlet standards platform independent application programming interfaces that are intended to enable software developers to create portlets that can be plugged into any portal supporting the standards.

Portlets – Liferay – Liferay Developer Network

The goal is to allow Portlets to be packaged into WAR files and deployed in portket standard way on any server implementing the specification. Learn More Got it! NOTE that this section has been updated since the original request.

OpenCV 3 by Example [ Video ] 3 hours 57 minutes. View Details Read Now. A Portlets Catalog is a set of portlets that are ready-to-use components for enterprise portals. InJava Portlet Specification 1. Like the Servlet specification, the Portlet specification will allow access to Enterprise Information Systems without imposing restrictions on the type of protocols.

The API will provide a URL-rewriting mechanism for creating links to trigger actions within a Portlet without requiring knowledge on how URLs are structured in the particular web application.

When you develop portlets for Liferay Portal, you can leverage all the features defined by the portlet specification. Liferay Portal does, however, provide utility methods that can access the ServletRequest and query parameters. This lets a portlet serve dynamic content without running the Render phase on all portlets on a page.

The portlet specification only provides a mechanism for a portlet to read its own URL parameters or those declared as public render parameters. Processes events triggered in the Action phase. It is expected that both specification leaders will fully share responsibilities specificwtion with group leadership, including group communications, decision making, and agreeing to the business terms for the RI and TCK. When this phase runs on one portlet, it also runs on all other portlets on the page.


This specification will establish a standard API for creating Portlets, thus avoiding locking in Portal developers in a specific implementation and allowing Portlets developers to reach a wider audience while reducing their development efforts.

Please help improve this article by adding citations to reliable sources. And because the portal controls page layout, you can reposition and resize one or more portlets on a page without altering any portlet code.

It is perfectly valid to speciification the tools JSR specifications offer suitability to the developers to reuse the code to maintain a set of JSR compliant portlets. Miller, Rui Miguel Forte Master the craft of predictive modeling in Specifciation by developing strategy, intuition, and a solid….

2. Java Portlet Specification (JSR)

JSR is the Java Portlet specification v3. Learn different Artificial Intelligence learning techniques with neural networks. We will tell you, however, how portlets differ from other types of servlet-based web apps. Views Read Edit View history. Essentials of Bitcoin and Blockchain [ Video ] 2 hours 42 minutes. Portlets instead access a javax.

Unlock course access forever with Packt credits. Each portlet phase executes different operations:. How do you feel about the new design? APIs and descriptors to support internationalization and localization are a fundamental specicication goal of this JSR.

The Expert Group will evaluate defining a Credential mapping service to allow the Portal application to access resources in other applications not supporting the notion of distributed sessions- on behalf of user.
