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.
