I want to share, in case that someone is googling for a solution here: I managed to create this configuration: DataSource bound by Spring, HibernateSessionFactory bound by Spring, Seam-managed Session by creating a Seam delegate component "sessionFactoryDelegate" that wraps Spring-bound SessionFactory and serve it via EL, like this: <persistence:managed-hibernate-session name="pecpSeamManagedHibernateSession" auto-create="true" session-factory="#{sessionFactoryDelegate.sessionFactory}"/> I would prefer another solution but current Spring integration apparently does not allow me to do this (is broken?).
