Question:What is the difference between JavaBean and EJB?

Answer:

A Java Bean is a software component written in the Java programming language that conforms to the JavaBeans component specification. The JavaBeans APIs became part of the “core” Java APIs as of the 1.1 release of the JDK.

The JavaBeans specification defines a Java-based software component model that adds a number of features to the Java programming language. Some of these features include:
.introspection
.customization
.events
.properties
.persistence

Enterprise JavaBeans (EJBs) are Java-based software components that are built to comply with Java’s EJB specification and run inside of an EJB container supplied by a J2EE provider. An EJB container provides distributed application functionality such as transaction support, persistence and lifecycle management for the EJBs.
