Do you know Enterprise Java Beans? Do you know about how containers manage the lifecycle of EJBs? Do you understand the difference between entity beans and stateless session beans? Do you know why we didn't mention stateful session beans in the previous question? EJB roleplay is a way to understand the lifecycle of EJBs. By interacting with others you "feel" the way things are organized. It's an interesting way to learn complex behavior for both newbies and experts.

Attendee background

Attendees may have any range of knowledge about EJB concepts. That is, they could be novices as well as experts. The goal is to bring these people together to get a shared understanding. Some basic programming knowledge should of course exist.

Format

Lectures with slides and active role-playing. See http://www.josuttis.com//talks/ejb12.jpg for an impression of the playing.
