Hi Murali, Session bean meant for your business process. It can do a simple thing like tax calculation or connecting to another bean etc. The session beans are verbs of your application. You cannot handle transaction management through session bean. At the best you can get the data from the database but you cannot do update existing record or adding a new record in the database.
The entity beans are nouns of your application. These are your persistence objects. It represents your permanent data. Entity beans are capable of handling the transactions. Each table in your database represents one entity bean and each instance of a bean represents a record in that table. You can use session beans for transaction but you have to go for Synchronized session beans.
