EJB applications

IBM WebSphere Application Server provides broad support for enterprise beans, including the Enterprise JavaBeans (EJB) 2.x specification. The EJB 2.x specification introduces a container-managed persistence (CMP) 2.0 component model, which provides a number of improvements to aid developer productivity and application performance. In addition, this product continues to fully support enterprise beans written to the CMP 1.1 programming model and deployed in previous versions of this product; applications can use CMP 1.1 beans, CMP 2.0 beans, or a mixture of both. CMP 1.1 beans can be directly carried forward in an EJB 1.1 ejb-jar module or may be repackaged and combined with CMP 2.0 beans in an EJB 2.x module.
