Transaction != Persistence Context As long as there is a persistence context, you can lazy load stuff. Just use the UserTransaction API or EJB3 transaction annotations to set transaction boundaries. The RENDER RESPONSE phase, and any data access not in the INVOKE APPLICATION PHASE (where your custom transaction assembly would most likely apply) is then executing effectively in auto-commit mode.
