The JavaBean is just a plain java class that complies with a few requirements (namely getter and setters, + public no-args constructor).
The EJB is much more sophisticated and lives inside a container. The container offers many services and take charge of most of the low-level tasks for you.

hi,
A EJB can be deployed and work as a standalone component.
A JavaBean can't be deployed, it's a part of a bigger system. This bigger system can be run. Think of it as a helper object.

java Bean is an ordinary class.
But EJB is designed to run in the J2EE framework & act as an enterprise component.
Hope i'm clear to you
