it will eventually be in the spec as a number of EG members have request for it. It is a no-brainer.
Unfortunately, I don't think it made it into EDR2 and Hibernate3 will need to support it as well.
Good to know it will be there. I understand that the spec is in development and a bit of a moving target right now. I'm just putting together a toy app to explore this stuff at the moment, but I'm looking forward to the day that I don't have to explain to coders why EJBs put 3 layers of indirection between them and what they need to get done ;)
