* Servlets and portlets are web based components that utilize Java for their implementation
* Portlets are managed by a portlet container similar to a servlet container
* Both of these components generate content, which can be static or dynamic
* Both portlets and servlets have a lifecycle that is controlled by the container
* The client/server model is used for both servlets and portlets
* The packaging and deployment are essentially the same
* The manner in which the classes are loaded and the class loaders that perform the work are also the same
* Lifecycle management is similar
* The Request and Response semantics are also similar
Here are some differences:
* Servlets can provide complete web pages, whereas portlets only provide fragments. These fragments are then aggregated to form a complete web page by the portal
* Portlets aren’t allowed to generated HTML code that contains tags such as base, body, frame, frameset, head, html, or title. The iframe tag can be used with caution.
* The user cannot access a portlet directly using a URL in the way that a servlet is accessed. Instead, the URL points to the page containing all of the portlets on one page
* Communication between the web client and the portlets is performed through the portal
* Portlets can be provided with buttons or controls to manipulate the portlets’ window states or portlet modes
* Multiple instances of a single portlet can be placed onto the same page
* Portlets support persistent configuration and customization
* Portlets also support user profile information
* Portlets support two scopes within the session; application scope and portlet scope
There are several things that servlets are allowed to do, but portlets aren’t. These include the following:
* Portlet aren’t allowed to set the character set encoding of the response
* Portlet also aren’t allowed to set the HTTP headers on the response
* Portlet cannot manipulate the URL of the client request to the portal
JSR 168 implementation on WPS,
life cycle of portlet,
portlet API
Request and Response(Action and Render phases), Advanced url generation,
user attributes(PUMA),
Themes and Skins(various jsp files),
inter portlet communication,
packaging of portlets and deployment tool,
portlet preferences,
portlet service,
portlet session with portlet scope and application scope,still more...depends on your implmentation. hope this helps.
What is Portal:
software architecture where a server-side component is used to aggregate content generated by small subcomponents called portlets.
A portal is a Web application that presents content from multiple sources. Portlets are Web components that generate content fragments (typically pieces of markup such as HTML, XML, or WML). By aggregating the content generated by many portlets, a portal is able to generate a single user interface which integrates many disparate sources.
Portlet Specification is built on top of the
Java Servlet Specification 2.3 and
Java Server Pages version 1.2
The Portlet, PortletConfig, PortletRequest, and PortletResponse interfaces
What is a Portlet? Explain its capabilities.
Portlets are pluggable UI components which are managed, displayed using a web portal.
Markup code fragments are produced by the portlets which are aggregated into a portal page.
A portlet resembles an application that is web based and is hosted in a portal. Email, discussion forums, news, blogs, weather reports are some of the examples of portlets.
The core implementation of the portal is UI, hosted by a Portal server. The HTTP requests, HTML responses, and returning appropriate portal pages are handled by the Portal UI. Enterprise Web application also can be handled by the Portal Server.
The portal architecture has the following: AISCCAR
Automaton Server, Image Server, Search Server, Collaboration Server, Content Server, Authentication Server, Remote Server,
Automaton Server: This server performs the management of job scheduling and implementation of a portal. It accesses all remote crawlers and profile services retrieved and stored from a remote database.
Image Server: This server hosts images and other web page content used by web services and a portal. With this configuration, large static files are to be sent directly to the browser without portal server impacts.
Search Server: This server indexes and searches all the information, applications, communities, documents, web sites through portal.
Collaboration Server: Web content publication and management for portals and web applications are supported by this server. Its functionality can be accessed by a remote web services through Enterprise Web Development kit.
Content Server: Publication and management of web content for portals and web applications along with form based publishing, branding, templates, content expiration is allowed by this server.
Authentication Server: This server handles the portal authentication for users and remote services can be accessed through EDK.
Remote Servers: Web services written using the EDK are hosted by remote servers. The servers can be in different countries, on different platforms and domains.
What is PortletSession interface?
User identification across many requests and transient information storage about the user is processed by PortletSession interace.
One PortletSession is created per portlet application per client.
The PortletSession interface provides a way to identify a user across more than one request and to store transient information about that user.
The storing of information is defined in two scopes- APPLICATION_SCOPE and PORTLET_SCOPE.
APPLICATION_SCOPE: All the objects in the session are available to all portlets,servlets, JSPs of the same portlet application, by using APPLICATION_SCOPE.
PORTLET_SCOPE: All the objects in the session are available to the portlet during the requests for the same portlet window. The attributes persisted in the PORTLET_SCOPE are not protected from other web components.
What is PortletContext interface?
The portlet view of the portlet container is defined by PortletContext. It allows the availability of resources to the portlet. Using this context, the portlet log can be accessed and URL references to resources can be obtained. There is always only one context per portlet application per JVM.
