I just noticed that eXo has announced the first portlet 2.0 container implementation. Great move on the part of eXo to get there first.
Kudos to them for that !
However, I am pretty disappointed with the quality of this release because I am yet to figure out how to get it running. After starting tomcat, all I see is a page which asks me to select some of the listed portlets. The listing however is empty (Windows XP, jdk 1.5, IE7/FF2, if it matters).
As for documents, they don't seem to exist :-)
