It's apache-tomee-plus-1.6.0.2 I have my data source defined in context.xml and persistence.xml refers it via JNDI.
I present you briefly with my setup hoping it will help you to figure out what's wrong. I'll provide you with the source code if you want further analysis. I have the Order Entity. I have a separate class called OrderManager. It is a stateful bean which has a EntityManager through @PersistenceContext (with Extended as the persistence type). I have a servlet which processes the requests and it has a EJB (EntityManager) injected. On Thu, Jul 24, 2014 at 7:06 PM, Rick Curtis <curti...@gmail.com> wrote: > Hrmm, odd.
