This chapter continues on from Chapter 8, Design and discusses the refinement of design elements into implementation elements. The key objectives of the implementation activities of the J2EE Developer Roadmap are as follows:
To define the organization of the implementation elements (including both source and executable code)
To produce and unit test the implementation elements
The Design Model elements we will refine during implementation include Design Subsystems (that represent enterprise components), Interfaces, Framework Components that (represent EJBs), and Design Classes (that represent servlets, JSPs, and Java classes).
The result of the implementation activities is the Implementation Model. The model contains representations ...
