Portlet developers can read this paper to see a side-by-side comparison of the Portlet API provided by IBM with the Websphere Portal V5.x product, and the JSR 168 Java Portlet Specification, which is developed through the Java Community Process. The paper describes the conceptual differences between the two APIs, provides specific examples, and discusses the relationship to the Web Service for Remote Portlets (WSRP) service. It also offers advice for programming portlets with the IBM Portlet API so you can easily convert them to the JSR 168 API.
This paper is provided As-Is. A reviewed, edited, and summarized version, which was also written by Stefan Hepper (published December 2003), is available on developerWorks; it is called Comparing the JSR 168 Java Portlet Specification with the IBM Portlet API.
