JavaOne: TS-7949: The New EJB 3.0 Persistence API
Got to this one late (lunch), so this is not full notes.
Extended Persistence Contexts
- Rescue the stateful session bean from obscurity
- natural cache of data that is relevant to a conversation
- allows stateful components to maintain references to managed instances instead of detached instances
Conversations
- A conversation takes place anytime a single user interaction spans more than one request
- sometimes helpful to capture conversation in object(s), can optimize, manage lifecycle, etc.
To be quite frank, the content of this session bored me, so I exited early. The basic summary is that if you are doing hardcore EJB and database stuff, you may want to check this topic out in more detail.
