I don't think the blog portlet will work on jboss 4.2.2 and portal 2.6.4. However that project isn't in development anymore; instead, there will be a feed aggregating system (without blog authoring). Check the Labs webpage in a week to see how it works. I'm very sorry for having not up-to-date information on the website!
And what is the advice in the current situation? I just set up a system with JBoss Portal 2.6.4 and need to integrate a blog solution.
How is the blog on the jboss.com pages done? It seems that the site runs with JBoss Portal as well....
Thx for any hints,
Any suggestions for a blog authoring solution?
