I did a search on the blog module with very few results. I noticed this http://www.jboss.org/index.html?module=bb&op=viewtopic&t=40760 and thought about Roller Weblogs found here: http://www.jroller.com/

I'm not a developer so I don't know much about the technology, but couldn't one just plug in the Roller Weblogger into the Jboss Nuke? Just a thought, because Roller has many features and mirrors Moveable Type in terms of functionality.
