[jboss-user] [JBoss Seam] - Re: Trouble Using <s:convertEntity/> on Glassfish

Thanks for the clarification. Seam really does have some neat features! I am trying to get to the root of my problem so have reverted to using the "jboss-seam-1.2.1.GA/examples/glassfish" example. I tried adding <core:entity-manager-factory name="dbFactory" persistence-unit-name="bookingDatabase"/> to the components.xml file expecting the example app to still work. However I got the following error: | javax.persistence.PersistenceException: java.lang.NullPointerException | at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:252) | at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:120) | at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:96) | at org.jboss.seam.core.EntityManagerFactory.startup(EntityManagerFactory.java:74) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | ... | Does anyone know what config I should tweak to get the entity-manager-factory working on the glassfish example? I suspect it is a visibility problem with the persistence.xml file and associated entities. However, it is late and I would like to stop experimenting for the night. Maybe once that works, I can try thinking about <s:convertEntity/> again. ;) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4051561#...
