Microcontainer Definition List

JMX Microkernel: The JBoss JMX Microkernel is a modular Java environment. It differs from standard environments like J2EE in that the developer is able to choose exactly which components are part of the environment, and leave out the rest.
POJO: A Plain Old Java Object (POJO) is a modular, reusable Java object. The name is used to emphasize that a given object is an ordinary Java Object, not a special object, and in particular not an Enterprise JavaBean. The term was coined by Martin Fowler, Rebecca Parsons and Josh MacKenzie in September 2000 in a talk where they were pointing out the many benefits of encoding business logic into regular java objects rather than using Entity Beans.
Java Bean: A Java Bean is a reusable software component that can be manipulated visually in a builder tool.
A Java Bean is an independent piece of code. It is not required to inherit from any particular base class or interface. Although Java Beans are primarily created in graphical IDEs, they can also be developed in simple text editors.
AOP: Aspect-Oriented Programming (AOP) is a programming paradigm in which secondary or supporting functions are isolated from the main program's business logic. It is a subset of object-oriented programming.
