EJB Fundamentals and Session Beans,discussed to this point for expressing business logic has been JavaBeans accessed from JSP and Servlet code. Java EE has a powerful facility dedicated to expressing the business logic of an application and for accessing a database using a JavaBeans-like concept. That facility is ., known as EJBs for short.

EJB Entity Beans,and message-driven beans. We then looked at session bean development in detail. In this chapter and the following one, we’ll focus on developing entity beans, which are the persistent data objects in an EJB application.

Bj?rn T. Asheim,Mario Davide ParrilliIn the previous chapters, you received a brief introduction to Java EE and got a chance to build a very simple JSP page. In this chapter, we’ll start to take a much more detailed look at JSP.

Interactive Markov Chains in Practice,The previous chapter introduced you to JSP and provided enough information to enable you to begin writing and using those web components. However, the previous chapter only scratched the surface of what can be done with JSP pages.

Networks and their ApplicationsIn Chapters 3 and 4, you learned about JSP pages, which are commonly used in Java EE web applications. Servlets are the other common component in Java EE web applications.

Networks and their ApplicationsThe previous chapter explored EJB entity beans, which are the persistent data objects in an EJB application. In this chapter, we will continue with EJB-related topics, including entity bean relationships, EJB QL queries, and JDBC with EJB applications.
