Chapter Review


This chapter began with a review of key EJB concepts and terminology and a discussion of the EJB life cycle in the WebLogic Server EJB container. Each of the EJB component types was identified, and a few simple examples were presented in preparation for the subsequent discussions.

The bulk of the chapter was dedicated to presenting WebLogic Server-specific features and capabilities related to EJB components . Many of these features are relatively new in the WebLogic Server product and require careful configuration to achieve the desired performance or reliability benefits. The discussion of each feature was accompanied by a best practice indicating its usefulness for typical EJB applications and highlighting any limitations or configuration recommendations.

How should you design your EJB application? Which WebLogic Server-specific configuration options should you employ to improve performance? In the vernacular of the J2EE architect, it depends. It depends on your specific requirements for performance, concurrency control, remote-interface availability, and many other issues. It is impossible to provide a single, overriding recommendation for EJB design or configuration. It s up to you to decide.

To help you make these important decisions for your project, the next chapter includes a discussion of the key application drivers, the selection of a business- tier architecture, and the appropriate configuration options for the example EJB application, bigrez.com .
