There has been recent discussion of bringing together the JDO and EJB persistence models. You can get up to speed on the JDO side of the discussion with Core Java Data Objects. Chapter 3, "Getting Started with JDO," covers how JDO is able to transparently persist instances of Java classes, the basic JDO interfaces and how they are related, how to define a Java class that can be used with a JDO implementation, and how to connect to a datastore.
