The document discusses the Portlet 2.0 JSR 286 specification and outlines some of the key new features it introduces over JSR 168, including the ability for portlets to communicate with each other through shared render parameters and events. It also covers additional capabilities like portlets being able to generate non-markup content through resource serving and better support for web frameworks and AJAX. The presentation provides an overview of portlet concepts and the limitations of JSR 168 that JSR 286 aims to address.
