Chapter 2. Inside the Web Tier
This chapter discusses the relationship between the architectural tiers and their roles in
an application. Special attention is given to the web tier, which
allows an application to communicate and interoperate with clients
over the Web. In particular, this chapter focuses on the physical and
logical aspects of designing and using a web tier for your
applications. The Struts framework is based on the Java Servlet technology and, to
a lesser extent, JavaServer Pages, and therefore is dependent on a
web container. For Struts developers, understanding how the web
container processes client requests is fundamental to a deeper
understanding of the framework itself. This chapter illustrates the
various components that are part of the web container and discusses
each component's responsibilities. |
