Yogender,
1)A servlet session is also called an HTTPSession. This is commonly used to store a user's data between requests. An EJB session is used if you want to store data in a stateful session bean.

2) Why would you want to store the user's data in two places? This adds extra complexity without any benefit that I can see.
