JavaBeans | | Javabeans may be used just like a stateless or stateful session bean. However, they do not provide the functionality of a session bean (declarative transaction demarcation, declarative security, efficient clustered state replication, EJB 3.0 persistence, timeout methods, etc). | | In a later chapter, we show you how to use Seam and Hibernate without an EJB container. In this use case, components are JavaBeans instead of session beans. Note, however, that in many application servers it is somewhat less efficient to cluster conversation or session scoped Seam JavaBean components than it is to cluster stateful session bean components. | | By default, JavaBeans are bound to the event context. | | Concurrent requests to session-scoped JavaBeans are always serialized by Seam. | So we can always use the data model objects as-is, i think. What might need a separate ejb3-wrapper and a maybe also refactor the IdentitySession a bit to support that external wrapper. So i think the first effort should be to try and wrap what we have into seam. If we need to update the way that IdentitySession's are created for that, no prob. If the whole identity component becomes dependent on ejb 3, that is a problem. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4027443#...
