Java Applications Using EJBs

Enterprise JavaBean (EJB) technology runs in Oracle Application Server Containers for J2EE, allowing developers to focus on implementing business logic rather than developing system-level functionality. Key features include:

Full EJB 2.0 implementation, which includes support for session, entity, and message-driven bean types
Container-managed persistence and container-managed relationship support for entity beans
Dynamic EJB stub generation on deployment
Enterprise archive (EAR) deployment
