The new EJB 3.0 (JSR-220) specification has enhancements that help address the inadequacies of the previous release, and it might even change your mind about using EJBs. This article helps you get the emerging EJB standard into perspective so you can evaluate it for your own environment. See how EJBs have morphed into elegant Plain Old Java Objects (POJOs). Find out what happened to JNDI lookups. Learn how Java 5 annotations reduce the deployment descriptor nightmare. See how container-managed persistence puts you on the fast track to beat the “object-relational impedance mismatch” dilemma. Take a look at the evolved EJB query language. For each key aspect of the new spec, you get a balanced, objective discussion of its technical merits and how it overcomes the shortcomings of the previous release.
