next chapter we'll take a closer look at options for J2EE architecture, and define a high-level architecture for the sample application.In Chapter 7 to Chapter 9 we'll look at data access options for use in J2EE applications, and how we can efficiently implement the ticketing application's data access requirements.In Chapter 11 we'll look at how a generic application infrastructure can be used to solve many common problems, and how it simplifies application-specific code.In Chapter 12 and Chapter 13 we'll look at implementing web interfaces in J2EE applications, using the reservation use case from the sample application to illustrate how to use the MVC architectural pattern.In Chapter 14 we'll look at J2EE application deployment, showing how to package the sample application and deploy it on JBoss 3.0.0.In Chapter 15 we'll look at meeting the performance targets identified above.
