Strange problem deploying stateless component to Jboss
I have a stateless session bean that I can't deploy to Jboss as a seam component. It worked not long ago, and I'm not sure what I changed to break it. Everything seems straightforward and I'm at a loss, any suggestions are much appreciated. Jboss is 4.2.2.GA and Seam is 2.0.2.SP1. Here is the error I'm getting:
02:34:24,597 INFO [Initialization] Installing components... 02:34:24,618 INFO [Component] Component: UserDAOBean, scope: EVENT, type: JAVA_BEAN, class: com.ccri.gotm.auth.dao.UserDAOBean 02:34:24,621

Earlier in the log I see this which is encouraging:
