Day 21. Developing a Complete Enterprise Application

Today, you'll develop a complete enterprise application. You'll apply different concepts you learned in the previous days to build an application that consists of Web components (JSPs and servlets), EJB components (session, entity, and message-driven enterprise beans), and the EIS tier (database tables).

The sample university registration system is an end-to-end application that handles the online course registration and enrollment process in a transactional e-commerce environment.

Today you'll see how to perform analysis, design, implementation, and deployment of the sample application. You'll undertake each of the following:

• Understand the application requirements

• Perform use case analysis

• Decide on a system architecture that meets the application requirements

• Identify the components in the multitier architecture and the interactions among these components

• Implement the components, and package and deploy the application
