Description
Jetspeed 2.1 already provides "pre" Portlet 2.0 ResourceURL support through implementing the Portals Bridges PortletResourceURLFactory interface.
This "old" PortletResourceURLFactory feature will still be supported for backwards compatibility but reimplemented natively as Portlet 2.0 ResourceURL.
For processing a ResourceURL, Portlet API 1.0 based portlets as being defined through an Portlet 1.0 version portlet.xml, will be served using the old solution by calling their portlet.render method.
Portlets defined through an Portlet 2.0 version portlet.xml will be invoked using the new ResourceServingPortlet.serveResource method.
