I have a session facade for my entity bean (and MySql DB) and I'm not sure about where to specify my transaction behavior, which will be container managed. Presumably I apply the transaction tags (e.g. RequiresNew) to the method in the Stateless SB (i.e. the session facade) that accesses the entity. How do I set the isolation level? And does this mean that I do not apply any transactional attributes on the entity bean.
