Linda DeMichiel together with Mike Keith again walking us through the new EJB3 API. I must say that I like the idea of the one, true, unified O/R mapping framework. Also providing a decent set of default values id really smart - the table mapping is reminiscent of Rails. I wonder what all the app server vendors think of the fact that it can be run outside of EJB? This is another reason that you most probably can get by with Spring in most cases which really must upset the app server vendors and especially JBoss.
