Hi Syed,
I think if u go through some book on EJB, the first thing u will get is the diff between JavaBean and EJB.
One of the diff is EJB's deployable where as beans are not.
Ejb's are more useful when u r having Transaction.
Some one correct me if Iam wrong

Dear Ones,
I would like to add something on this.
Java-Beans are meant to provide general purpose components, whereas the EJB's are meant to provides a format for a highly specialized business logic components.
Java-Beans can be executed anywhere either on client or on server, whereas EJB's can be executed only at server side(specifically business logic tier)
Java-Beans provide the java libraries and other services with container.whereas EJB's provides the persistence,security, Connection pooling etc.
Hope this will clear your doubt.
Kutub.
