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.
 
It is sorta covered in the JavaRanch Style Guide.
