Standard portlet API

The Java Portlet Specification addresses the requirements of aggregation, personalization, presentation, and security for portlets running in a portal environment. Version 1.0 of the Java Portlet Specification was approved by the Java Community Process in October 2003 as JSR 168. The purpose of the specification is to solve the problem of portlet compatibility between portal servers offered by different vendors.

WebSphere Portal Express includes a portlet runtime environment that supports portlets developed according to the Java Portlet Specification, hereafter called standard portlets. The portlet container for standard portlets is based on Pluto, which is the reference implementation for portlet containers supporting the Java Portlet Specification. For more information about Pluto, see http://portals.apache.org/pluto/.

With WebSphere Portal Express there are some IBM specific parameters for portlets available. For more information about these parameters refer to Deployment descriptors, under the section Reserved parameter names.

The following topics provide specific information about the implementation of the standard portlet API within WebSphere Portal Express.
