Chapter 5. Technology options
In this chapter, we take a look at the Web application technology options you
should consider. The recommendations are guided by the demands of reuse,
flexibility, and interoperability, and subsequently are based on the open industry
standards outlined by Java 2 Platform, Enterprise Edition (J2EE). Many of the
choices continue to evolve and expand as the J2EE specification matures to
include a broader view of the enterprise architecture. These recommendations
are based on the J2EE1.3 specification and parts of the J2EE1.4 specification.

Our discussion of technology options is organized along the enterprise
application tiers shown in Figure 5-1:
Web client technologies for providing client-side presentation.
Web application server technologies for providing server-side presentation
and business logic.
Integration technologies for providing access to the enterprise tier.
