jsr 286 portlet lifecycle methods





3. Understanding JSR 286 Programming What is JSR 286, and what is Alternatives APIsMVC, The Portlet Interface, Our first Portlet. Lifecycle of a Portlet, How the portlet handle aProcessing APIs, the RenderResponse Interface, PortletURL Portlet Processing method the processAction So as long as your jsr168 portlet doesnt depend on the value returned by getProtocol() youre safe (ie every jsr168 portlet is a jsr286 portlet). The posts you see seem to be logical as jsr286 is a newer spec and there are some features that make jsr268 portlet not a jsr168 portlet. The javax.portlet.Portlet interface defines four lifecycle methods, with the init and destroy methods used to allow a developer to take action when a portlet is first loaded, or when a portlet isAs a JSR-286 portlet developer, you will never create a class that simply implements the portlet interface. To set HTTP header information in your JSR 286 portlet, use the setProperty and addProperty methods of the PortletResponse.When setting headers in the render lifecycle phase, portlets should set the header in the render headers part or simply override the GenericPortlet.doHeaders One of the major new feature added in the Portlet technology by the JSR 286 is the Portlet Filter. A portlet filter is a Java component that can be used to modify portlet request and response before/after any lifecycle method of the portlet is being executed. Any JSR-168 or JSR-286 portlet operates as it is mandated by the respective specifications inside the portal.This file must adhere to its definition in the JSR-286 Portlet Specification.Application Monitoring Filter supports four lifecycle phases as the order below: ACTIONPHASE Concepts Portlet 1.0 (JSR-168) specification Whats new in Portlet 2.0 ( JSR-286) JBoss Portal Enterprise Portal. Runs on top of a servlet container Manages portlets on behalf of portals: Exposes portlet metadata to portals Manages portlet lifecycle and state Handles portlet September 27, 2014. Portlet Lifecycle. Multiple phases associated with HTTP GET/POST operations Concept is implicitly defined by JSR 286 Portlet Specification 2.0 Will be explicitly defined by JSR 362 Portlet Specification 3.

0. JSR 286 (Portlet 2.0) defines a lifecycle for events, so that eventing is possible between portlets that are in different web applications.The portlet container calls the processEvent() method for each event targeted to the portlet with an EventRequest and EventResponse object. Liferay portal is designed to deploy portlets that adhere to the Portlet API ( JSR-286).The life cycle of a portlet is expressed through the init, processAction, render, and destroy methods of the Portlet interface The specification also stated that render parameters must be set by the performAction method and that the portlet container may only pass those render parameters to the portlets render method.

Many portlet developers believed that the Portlet 2.0 specification ( JSR 286) The JSR 286 specification helps define inter portlet communication in two ways. Before we get into the details of it, lets see what interportlet communication is.Events are a life cycle operation which gets triggered before rendering phase. The portlet can issue an event via setEvent method in the action Announcements. Upcoming class: JSR 286 Portlet Development. IBM WebSphere Application Server 8.5 Administraion.In this course, you will learn how to design and develop standards based portlets by method of rigorous examples. The expert group of JSR 286 consists of all the major commercial and open-source portal developers, portlet bridge developers, and portlet framework developers.Version 2.0 now introduces a new URL type, resource URLs. Resource URLs trigger the lifecycle method, serveResource, on the The Portlet provides the additional optional lifecycle interfaces EventPortlet and ResourceServingPortlet that the portlet can implement. Basic four lifecycle methods. JSR-286: Portlet Filters. Very similar to Servlet Filters both in definition and API Filters can be applied to multiple lifecycles Filters can be chained Configured with Container runtime option. javax.portlet.renderHeaders (default false). Override the GenericPortlet.doHeaders method for In Portlet URL, what is pplifecycle? pplifecyle holds integer value and represents the portlet lifecycle phase that portlet belongsPortlet 1.0 did not offer any standard method for portlets to communicate with each other. Portlet 2.0 (JSR 286 ) addresses this issue with 2 different javax.portlet.tck.beans.JSR286DispatcherTestCaseDetails. By T Tak. Here are the examples of the java api class javax. portlet.tck.beans.JSR286DispatcherTestCaseDetails taken from open source projects. Create a new page in the portal and add the JSR 286 Overview portlet to the page. Watch the Tomcat console for message indicating the render method is being called.The Event Phase is used to process any Events triggered during the Action phase of the portlet lifecycle. Nilang December 16, 2014 0 Comment JSR-168, JSR-286, Lifecycle Methods, Liferay Portlet, Portlet, Portlet Lifecycle, Portlet Phase. Portlet performs unique operation in each lifecycle execution. JSR 286 based portlets flow. By overriding the major methods of GenericPortlet class and adding loggers on each method entry, we can easily view the flow of the portlets lifecycle. After deploying the portlet, when it is being invoked for the first time (by visiting a page on which it is added) HI, We are using webcentre portlet producer appliaction and creating JSr 286 portlets. Using Jdeveloper .I store my configuration in .properties file. Now I want to load this file only once, so I decided to load it in init(poerletConfig) method. The JSR 286 specification helps define inter portlet communication in two ways. Before we get into the details of it, lets see what interportlet communication is.Events are a life cycle operation which gets triggered before rendering phase.
