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.

Depending on how you develop speclfication package your portlet, however, it may not usr able to run on other portal containers.
Unlock course access forever with Packt credits. You can place multiple portlets on a single page. For a description of the Portlet technology, refer to section 2. Another difference is that portlets run only in a portal server, like the one in Liferay Spscification. Liferay Portal does, however, provide utility methods that can access the ServletRequest and query parameters. OpenCV 3 by Example [ Video ] 3 hours 57 minutes. It was released in June Portlets can be placed on pages by users or portal administrators, who can place several different portlets on a single page.
However, it does not address aggregation, security and personalization. Client agnostic Support for multiple types of clients multi-device Simple Portlet API Support for Localization and Internationalization Hot deployment 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.
The Portlet specification will restrict the use 18 functions provided by the Servlet API to a subset that makes sense for components providing fragments of a markup page. The Render phase runs when any portlets on the page complete the Action or Event phases. The Portlet specification will define the different components for Portal Computing, their interaction, lifecycle and semantics.
The recently released Java Portlet Specification 3. Compared to servlets, portlets also have some other key differences.
Do you specificatiln us your consent to do so for your previous and future visits? Once sprcification portlet processes all events, the portal calls the Render phase on all portlets on the page. The portlet can be on a page that contains other portlets. Even so, the advantages of modularity are so great that we still recommend you develop your portlets as OSGi modules. For those who want to adopt portals certainly need many and variety of portlets to deploy and run.

We recommend the latter, so you can take advantage of the modularity features inherent in OSGi. Also, it will define the minimum set of possible window states for a Portlet such as normal, minimized, maximized, etc.
The Portlet specification will define a Portlet API that provides means for aggregating several content sources and applications front ends.
Liferay leads in this space by having a member in the Expert Group. For a detailed description of these features, see the tutorial OSGi and Modularity.
