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.
  • The Enterprise JavaBeans architecture will define the contracts that enable tools from multiple vendors to develop and deploy components that can interoperate at runtime.
  • The Enterprise JavaBeans architecture will make it possible to build applications by combining components developed using tools from different vendors.
  • The Enterprise JavaBeans architecture will provide interoperability between enterprise beans and Java 2 Platform, Enterprise Edition (J2EE) components as well as non-Java programming language applications.
  • The Enterprise JavaBeans architecture will be compatible with existing server platforms. Vendors will be able to extend their existing products to support Enterprise JavaBeans.
  • The Enterprise JavaBeans architecture will be compatible with other Java programming language APIs.
  • The Enterprise JavaBeans architecture will be compatible with the CORBA protocols.
