JavaBean - an API for objects which expose their properties via standard naming convention (getXXX(), setXXX(), isXXX()). These properties can be determined at runtime via reflection and introspection. For true JavaBeans, they should be Serializable and have a default constructor. The orginal intent was to make them easy for tooling (tools could discover their properties, expose them to configuration, etc.).
EJB - an "enterprise" api for distributed objects. Provides a standard approach to building such objects and allowing an EJB container (EJB application server) to manage the lifecycle of the beans. EJB's provide persistance, scalability, and distributed transaction support (via the container).
