Since you’re reading this book, you obviously have some interest in Java EE, and you probably have some notion of what you’re getting into. For many fledgling Java EE developers, Java EE equates to Enterprise JavaBeans (EJBs). However, Java EE is a great deal more than just EJBs.
While perhaps an oversimplification, Java EE is a suite of specifications for APIs, a distributed computing architecture, and definitions for packaging of distributable components for deployment. It’s a collection of standardized components, containers, and services for creating and deploying distributed applications within a well-defined distributed computing architecture. Sun’s Java web site says, “ Java Platform, Enterprise Edition 5 (Java EE 5) defines the standard for developing component-based multitier enterprise applications.
As its name implies, Java EE is targeted at large-scale business systems. Software that functions at this level doesn’t run on a single PC—it requires significantly more computing power and throughput than that. For this reason, the software needs to be partitioned into functional pieces and deployed on the appropriate hardware platforms. That is the essence of distributed computing. Java EE provides a collection of standardized components that facilitate software deployment, standard interfaces that define how the various software modules interconnect, and standard services that define how the different software modules communicate.
