Based
on the Enterprise JavaBeans (EJB)
specification, enterprise

®WebSphere
® Application Server provides broad
support for enterprise beans, including the EJB 2.x and EJB 3.0 and
EJB 3.1 specifications. The EJB 2.x specification includes a container-managed

improvements to aid developer productivity and application performance.
The EJB 3.0 and 3.1 specifications simplify the development of business
logic and data handling for enterprise applications.
This
task lists the steps needed to implement EJB 2.x application in WebSphere Application Server,
