Difference between EJB 2 and EJB 3
I know we dont implement home and remote interfaces.1)Do we have ejb-jar.xml in EJB 3.0? If it is not there, do we have anuthing else?
2) What is the flow in EJB3.0. That is
the clientClass using the JNDI name looks for appropriate bean and operates. where is the deployed jar file placed. Is it in client side or server side. Where is it used in EJB lifecycle.
3) Why do we have Remote and Home interfaces in EJB 2.x? What do they exactly do?
4) How does the bean lookup start in EJB 3 and how it differs in EJB 2?
please explain me like this for the 4th Question,
In EJB 2.x when first client makes a call, it connects to the server and looksup for the JNDI name in the appropriate jar..
