JBoss Portal does not offer today all those tools as they would represent a significant effort in term of productization and resource behind it, it's an whole other world.
What we do provide is a good Forum and we are about to provide also a Blogging portlet.
Maybe other users of this forum can provide some valuable response.
I am getting error Jboss Wiki portlet (wiki.war) in Jboss Portal 2.4.2.
Can any body help me on this?
Try in the Wiki Portlet forum, and specify your errors otherwise they won't be able to help you
