EJB is an acronym for enterprise java bean. It is a specification provided by Sun Microsystems to develop secured, robust and scalable distributed applications. To get information about distributed applications, visit RMI Tutorial first.

Enterprise Java Beans (EJB) is a server-side component technology for Java EE based systems (JEE). Beans are business logic components that implement a standard interface through which the bean is hooked into the bean container (= runtime object for bean). A Java class implementing one of the standard bean interfaces is an Enterprise Java Bean.

The business logic is the code that fulfills the purpose of the application. In an inventory control application, for example, The enterprise beans might implement the business logic in methods called check Inventory Level and order Product. Enterprise JavaBeans is Lightweight The EJB 3.1 specification is a lightweight Plain Old Java Object (POJO) programming model. The only requirement is the existence of the @Stateless, the @Stateful, or the (less common) @Singleton annotation. The simplest possible bean looks like this: Learn how to code, package, deploy, and test functional Enterprise JavaBeans with the latest edition of this bestselling guide.

Enterprise JavaBeans (EJB) technology is the server-side component architecture for Java Platform, Enterprise Edition (Java EE). EJB technology enables rapid and simplified development of distributed, transactional, secure and portable applications based on Java technology. EJB 3.0 Specification Final Release

The Enterprise Java beans architecture is a component architecture for the development and deployment of component-based distributed business applications. Applications that are written using the Enterprise Java beans architecture can be written once, and then deployed on any server platform that supports the Enterprise Java beans specification.
