On the blueprint stuff, I'll repeat from an earlier thread. This should just be another facade on the MC like the spring-int project is. There is no reason to re-implement it when we already know there is a mapping from the spring-int example. Its just a change of namespace and some xml element/attribute names. :-) Any missing features/metadata should be implemented in the MC. In fact, from my (incomplete ;-) understanding of blueprint, its basically two different injection mechanisms in one xml file. One using a "Spring" type api and one using an "OSGi" type for the two different mechanisms. When Ales has this working, you should able to use either type to inject any service within JBoss. Just choose your poison. ;-) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4266347#...
