I was working on web project where I had the persistence layer in the web container itself and hibernate was used to persist data, there is a new requirement of introducing Session bean >> DAO >> Hibernate for persistence, do I have to move all my java beans and mapping files .hbm.xml to EJB container.

don't know if this is best practice but I have the DAO, POJOs and Mappings inside a MBean service and access the DAO objects with my Sessionbeans.
For MBean service take a look at using Hibernate with JBoss

I am using this approach in IBM websphere, I don't know whether there is any MBean concept in there.
