For a long time, Java Enterprise Edition (Java EE) has been the platform of choice across industries (banking, insurance, retail, hospitality, travel, and telecom, to name a few) for developing and deploying enterprise business applications. This is because Java EE provides a standard-based platform to build robust and highly scalable distributed applications that support everything from core banking operations to airline booking engines. However, developing successful Java EE applications can be a difficult task. The rich set of choices provided by the Java EE platform is daunting at first. The plethora of frameworks, utility libraries, integrated development environments (IDEs), and tool options make it all the more challenging. Hence, selecting appropriate technology is critical when developing Java EE–based software. These choices, backed by sound architectural and design principles, go a long way in building applications that are easy to maintain, reuse, and extend.
This article takes a tour of the fundamental aspects of Java EE application architecture and design. They form the foundation on which the entire application is developed.
