After the client get Home stub from the server, it does not need to JNDI lookup to the server to get a reference to the EJBHome interface... As you see on that page of the HF
EJB, the client need to get a reference to the home in order to get connection with the EJBObject to call mehtods on beans...
Hope it helps..
