Preface
This document is a resource for software developers who develop applications that include WebLogic Server EJBs using the Jakarta Platform, Enterprise Edition.
Audience
This document is a resource for software developers who develop applications that include WebLogic Server EJBs. It is assumed that the reader is familiar with Jakarta EE and basic EJB programming concepts.
The document mostly discusses the EJB 3.2 programming model, in particular the use of metadata annotations to simplify development. This document does not address EJB topics that are different between versions 2.x and 3.x, such as design considerations, EJB container architecture, entity beans, deployment descriptor use, and so on. This document also does not address production phase administration, monitoring, or performance tuning.
Note:
The EJB 3.2 specification provided in Java EE 8 provides the same functionality as the Jakarta Enterprise Beans 3.2 specification. All references in this document to EJB 3.2 can be interpreted as references to the Jakarta Enterprise Beans 3.2 specification.Parent topic: Preface

Diversity and Inclusion
Oracle is fully committed to diversity and inclusion. Oracle respects and values having a diverse workforce that increases thought leadership and innovation. As part of our initiative to build a more inclusive culture that positively impacts our employees, customers, and partners, we are working to remove insensitive terms from our products and documentation. We are also mindful of the necessity to maintain compatibility with our customers' existing technologies and the need to ensure continuity of service as Oracle's offerings and industry standards evolve. Because of these technical constraints, our effort to remove insensitive terms is ongoing and will take time and external cooperation.
