With the 3.0 version of EJB, Java's guardians have endeavored to make persistence a gentler beast that borrows the best from other ORM frameworks that have long curried favor with the community.

lthough the EJB 3.0 specification has yet to be released, it is already generating much interest in the software development community by both proponents and opponents alike. All recognize the need to find more productive methods for developing software; the debate centers on whether, and to what extent, EJB 3.0 will play a role in this new landscape. Debate notwithstanding, the release of the EJB 3.0 public draft and preliminary support in JBoss mean that now is a great time to explore this influential technology. In fact, reports of the use of EJB 3.0 in production systems are already emerging.
This article is the second in a three-part series exploring EJB 3.0 as defined in the public draft. Each article will introduce you to particular concepts from the specification and walk you through the implementation of these techniques using JBoss.
