A portlet is a Java technology based web component, managed by a portlet container, that processes requests and generates dynamic content. Portlets are used by portals as pluggable user interface components that provide a presentation layer to Information Systems. From: Java(tm) Portlet Specification 1.0 (JSR-168)
A portal-based application that supports autonomous functionality. Liferay Portal ships with over 50 useful, pre-bundled portlets.
A mechanism used to readily integrate content, applications and processes into portals. Portlets provide a low-level, point-to-point integration approach by accessing program application programming interfaces, Structured Query Language statements, Web services and more. Web services and Java provide mechanisms for enabling portlets written for one vendor's portal to run unchanged in another vendor's portal. Emerging standards to enable portlet interoperability include Java Specification Request (JSR) 168 and Web Services for Remote Portlets (WSRP). See

a type of application that can be accessed through a small box or window in a portal page. Portlets provide access to specific services or information, for example, a calendar or news feed.
Component that generates fragment
A portlet is a component of the portal in which certain information within the site of the portal can be displayed in the browser. Thus the portlet is able to draw its data from the local web server or other data source. The following views describe the features of the portlet closer: 1. From the user's point of view a portlet is an application which he or she is able to display and configure in his (or her) own portal site to show personalized data. 2. From the Content Manager's point of view a portlet is a possibility to provide selective content. 3. From the Portal Manager's point of view a portlet is a content container. This container is registered in the portal, so that a user can apply it. 4. From the portal's point of view a portlet is a displaying component within a page. 5. From the programmer's point of view a portlet is a code fragment. The code fragment is completed on a portal server and supplies the portlet with content.
Related Terms: enterprise portal, CGI A way of packaging small software components so they can easily be used and reused as part of an enterprise portal. Some companies package their search engine as a portlet, so that owners of different parts of the enterprise portal can easily add search to their section. In some ways a portlet acts as a CGI.
Portlets are pluggable user interface components that are managed and displayed in a web portal. Portlets produce fragments of markup code that are aggregated into a portal page. Typically, following the desktop metaphor, a portal page is displayed as a collection of non-overlapping portlet windows, where each portlet window displays a portlet.
