Sun has posted the proposed final draft version of
JSR-286 Java Portlet Specification 2.0 . New features in 2.0 include:
- Events – enabling a portlet to send and receive events and perform state changes or send further events as a result of processing an event.
- Shared render parameters – allowing portlets to share render parameters with other portlets.
- Resource serving – provides the ability for a portlet to serve a resource.
- Portlet filter – allowing on the fly transformations of information in both the request to and the response from a portlet
