The role of formal methodologies in your J2EE development projects depends on the size of your team, the length of your project, and the number of artifacts you need to produce during analysis and design. RUP and XP are good examples of two ends of the methodology spectrum, and we noted the conditions under which each is most applicable. More importantly, we also abstracted a few common principles from existing methodologies that can be used in the creation of your own process or the customization of an existing one.

In section 1.2, we took a brief tour of the categories of tools required in J2EE development and pointed out a few popular choices in each category. Many of these are open source and widely used, even in conjunction with commercial products. Others are popular, commercial products that either integrate well with your chosen server or provide functionality not readily available in open source tools. The goal here was to create a checklist of required tools and identify any holes in your development environment in this regard.

Section 1.3 discussed complicated issues regarding the testing and deployment of a J2EE application. We discussed useful approaches to testing various components and deploying them to your server environment, with an emphasis on build-time processes.

From here, we turn our attention to the specifics of using XML technology in the J2EE environment. Remaining chapters assume your mastery of the material in this chapter and demonstrate in detail the integration of J2EE and XML at each layer of an n-tiered architecture.
