Maybe it is a lack of docs... I already use most of tomee components, but the "glue" (pom.xml, web.xml, etc.) is hard to find at first...
I recently tried to use OWB 1.2 instead of 1.1.6 and the upgrade track is not very clear. It is not a drop-in replacement... My project uses latest myfaces 2.1, latest corresponding CODI and Tomcat 7. Well, maybe it is a curse of those great java projects. Great features, great performance, but steep learning curve...
