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.

A year ago, the article Asynchronous Rendering of Portlet Content With Ajax Technology demonstrated how to apply Asynchronous JavaScript and XML (Ajax) to portlets. Since then, Ajax has become increasingly popular in the software arena and many new Ajax technologies have emerged. Examples are JavaScript libraries and toolkits, such as the Dojo Toolkit, the Yahoo! UI Library, the Google Web Toolkit, Script.aculo.us, and DHTML Goodies. In addition, new standards bodies like Open Ajax and the Dojo Foundation are key players. In light of the many developments in the past year and the host of feedback on how to use Ajax in portlets, this article describes several helpful tips and practices on how best to exploit Ajax in portlets that comply with the Java Specification Request (JSR) 168: Portlet Specification.

What is the PortletBridge Portlet? The PortletBridge Portlet is a JSR 168 compliant portlet that allows a downstream web site to be proxied as a portlet. By default it only displays the content of the BODY but custom XSLT can be used to transform the data from the downstream site. What is the difference between the PortletBridge Portlet and an IFrame There are several differences between using an IFrame and the PortletBridge Portlet. Probably the biggest advantage to using an IFrame is that it is simpler than the PortletBridge Portlet and the downstream site will often be more faithfully rendered. There are however several advantages to using the PortletBridge Portlet.
