If this is the case, then don't forget to add the persistence namespace to your XML namespace config: | | xmlns:persistence="http://jboss.com/products/seam/persistence" | | <persistence:managed-persistence-context name="entityManager" | auto-create="true" | persistence-unit-jndi-name="java:/dvdEntityManagerFactory" /> Please add this to the seam2migration.txt, I spent one day on this.
