Summary and Preview
We've covered a lot of ground in this chapter. We've examined how the J2EE technologies introduced as the solution to the problems seen in Chapter 2 form a coherent MVC architecture and how the principles of application layering can be applied to make applications manageable, maintainable, and testable. In the next chapter, we begin to look more closely at the Servlet API: the first of the J2EE technologies that form the focus of this book.
