Ejb object is a server-side object,and it conatins business
methods,that is why we need to call ejb object as a business
component.

Ejb objects are used to access the Business logic methods 
defined by the user in the bean. client gets the reference 
of the object using JNDI, and cast the object as the 
HomeObject and access the methods in the bean.

EjbObject is an object which implements our component 
interface.The container creats it when we call create 
method on home stub.It contains business methods.It is a 
beans body guard.

EJB object implements Component Interface. It is created by 
the container when create() method is called by the Home 
interface. EJB object contains the business methods present 
in the bean class. Hence client request invokes the 
business method on bean via the EJB object.
