Architectural Overview
Overall Goals: The Enterprise JavaBeans (EJB) architecture has the following goals: • The Enterprise JavaBeans architecture will be the standard component architecture for building distributed object-oriented business applications in the Java™ programming language. • The Enterprise JavaBeans architecture will support the development, deployment, and use of web services. • The Enterprise JavaBeans architecture will make it easy to write applications: Application developers will not have to understand low-level transaction and state management details, multi-threading, connection pooling, or other complex low-level APIs. • Enterprise JavaBeans applications will follow the Write Once, Run Anywhere™ philosophy of the Java programming language. An enterprise bean can be developed once, and then deployed on multiple platforms without recompilation or source code modification. • The Enterprise JavaBeans architecture will address the development, deployment, and runtime aspects of an enterprise application’s life cycle.
