Implement EJB 2.x applications

Use this task when we are implementing EJB 2.x applications.

Based on the EJB specification, enterprise beans are Java components that typically implement the business logic of J2EE applications as well as access data. IBM 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 persistence (CMP) 2.0 component model, which provides a number of 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, including tuning and troubleshooting tips.

1. Migrate enterprise bean code.
   

2. Develop EJB 2.x applications.
   

3. Assemble EJB 2.x applications.
   

4. Deploy EJB 2.x applications.
   

5. Administer EJB 2.x applications.
   

6. Secure EJB 2.x applications.
   

7. Tune EJB 2.x applications.
   

8. Troubleshoot EJB 2.x applications.
