You now know some of the common patterns that can be applied in J2EE applications. Using this knowledge, you can analyse the case study followed throughout the book to see how they can be applied.
Patterns are usually best understood in context. It helps to understand the intention of the design (and its associated code) and what it is trying to achieve so you can understand why a particular pattern helps in that situation. By examining the code for the case study, this section intends to
Identify some of the places where J2EE patterns have been applied in the case study
Examine some of those patterns in detail, including how the pattern looks in code
Consider what other patterns could have been applied ...
