Portlet

A portlet is a Web-based component that will process requests and generate dynamic content. The end-user would essentially see a portlet as being a specialized content area within a Web page that occupies a small window in the portal page. Depending on the content nature of the Web site providing the portlet you could use this area to receive different types of information such as travel information, business news, or even local weather. The portlet provides users with the capability to customize the content, appearance and position of the portlet. To create a portlet application, you should be a J2EE developer with a background in Java Server Pages (JSP), JavaScript and HTML, and have a knowledge of Enterprise Java Beans.
