Gavin, jip, the fix did the trick. Thanks ! A question along that line: Do I still configure the persistenceUnitJndiName as previously ? e.g. <property name="persistenceUnitJndiName"> | java:/EntityManagerFactories/napEntityManagerF | </property> | In the examples I see that anonymous wrote : EntityManagerFactories does not appear anymore... | <component name="entityManager" | auto-create="true" | class="org.jboss.seam.core.ManagedPersistenceContext"> | <property name="persistenceUnitJndiName">java:/blogEntityManagerFactory</property> | </component> | Thanks for the quick fix !
