But you can still use them if you want to. If it is necessary you can still have a session bean as a wrapper around the EntityManager. I sometimes use this pattern, if the retrieving of entities is more complex and does happen - at least sometimes - outside of seam. This is useful if you have MDBs and you don't want them to depend on seam so you can deploy them on another AppServer more easily.
