Hi Rahul,
References having nothing to do with local/remote calls. They are
inroduced to make the code portable. Suppose you have a bean whose JNDI name
is "MyBean" and suppose there were no references, then you will lookup thru
JNDI name directly. Now at deployment time, if you find that this JNDI name
is already being used, then you will have to change your code as well as the
deployment descriptor. References help you here. If you define the
references, you lookup thru references and and in the deployment descriptor
you map the reference to the actual JNDI name on the server. So, in case the
JNDI name is not available for you, you make the change in deployment
descriptor alone. So it acts as a proxy only.
Hope I was able to clear your doubts.
Regards,
Rupesh.
