The Fundamentals of Enterprise Beans

If Enterprise Beans were airline passengers, they would all fly first class.

Enterprise Beans are application components that run on the Java EE server in the most cosseted components in any of the Java platforms. Like regular Java classes, they have constructors to instantiate them, and methods to process information and perform tasks. Unlike regular Java classes, they run in the luxurious environment of the Enterprise Bean container, which takes care of a variety of potentially complicated tasks that typically confront the developer of a server application.
