Seems like you are on the right course, its perfectly possible to introduce more layers into a Seam app - we just find its normally not necessary. You will loose some of Seam's nice features if you remove persistence too far from it (e.g. conversationally scoped persistence contexts). I would avoid dragging Spring in unless you have to.
