Portlets are pluggable user interface software components that are displayed in a web portal. For example, a portlet may be a page element showing the wether forecast.
Note how the portlet occupies only a part of the portal page. This is the primary difference between a portlet and a servlet. A portlet is meant to occupy only a part of the web page. And a portal web page consists of multiple, different portlets.
A number of vendors provide commercial implementations of the portlet container. Some of the leading vendors are IBM, Oracle, Vignette Corporation, JBoss, and Software AG. These vendors provide standards-based implementations as well as extensions not yet approved by the standards body. In addition, a number of open-source portal solutions support JSR168, such as Apache's Jetspeed-2 Enterprise Portal
