The Portlet sample wiki page has been updated recently to show off the flexibility of our theme API and showcase JBoss Portal support for existing web frameworks.
I have added two new themes that can be downloaded and deployed easily by following this section of the reference guide. One of the themes is the actual one used in the reference guide example and the other is the one used in our portal webinar demo, you can view recorded here.
The sample portlets include SpringMVC, Struts, and MyFaces portlets. I also added a freebie RSSPortlet that displays RSS content and is configurable from its own portlet.xml.
Hopefully this will help some of you implement framework-based portlets and custom themes in Portal using these examples.
