JSR-168 is a collection of Java APIs for portlet developers. There are a number of reasons to design JSR-168 portlets that adhere to the specification. Portability is an obvious benefit. Code written according to the specification will be easier to move to among portal servers. The majority of Java-based portal servers support JSR-168 portlets. Another benefit is easier federation. Exposing JSR-168 Portlets via Web Services for Remote Portlets (WSRP) producers is easier when portlets adhere to the JSR-168 specification. WSRP provides a standard to federate portlet content via Web services. JSR-168 and WSRP 1.0 portlet capabilities are tightly coupled. JSR-168 to WSRP portlet bridges utilize JSR-168's URL rewriting APIs. This article illustrates best practices for developing JSR-168 portlets for portability.

JSR 168 defines portlets as Java-based Web components, managed by a portlet container, that process requests and generate dynamic content. Portals use portlets as pluggable user interface components that provide a presentation layer to information systems.

This article will walk through the development of a simple portlet application to demonstrate the inner workings of a compliant portlet.

Portals Bridges provides support for JSR-168 compliant Portlet development using common web frameworks like Struts, JSF, PHP, Perl and Velocity.
