1.1 Document Scope and Audience

This document is a resource for software developers who develop applications that include WebLogic Server Enterprise JavaBeans EJBs, Version 3.0. The document mostly discusses the new EJB 3.0 programming model, in particular the use of metadata annotations to simplify development. The document briefly discusses the main differences between EJB 3.0 and 2.X for users who are familiar with programming EJB 2.X and want to know why they might want to use the new 3.0 programming model. This document does not address EJB topics that are the same between versions 2.X and 3.0, such as design considerations, EJB container architecture, deployment descriptor use, and so on. This document also does not address production phase administration, monitoring, or performance tuning. For links to WebLogic Server documentation and resources for these topics, see Section 1.3, Related Documentation. It is assumed that the reader is familiar with Java Platform, Enterprise Edition Java EE Version 5 and EJB 2.X concepts.
