Summary
Portlets are Java technology based web components,
managed by a portlet container,that process requests and generate dynamic content.They are used by portals as pluggable user interface components that provide a presentation layer to Information Systems.After servlets portlets are the next step in web application programming,as they allow the integration of different applications into one consistent view for the end-user.They enable modular and user centric web applications and thus go beyond the servlet model where the web application is one monolithic block.In this article we present the JSR 168 Java Portlet Specification and explain its underlying concepts.We show a Portlet example and discuss how portlets interact with other Java technologies.
