I am new to ejb's.I want some information regd isolation levels
ejb container provides 4 levels of Transation isolation.
Transaction_read_uncommited
Transaction_read_commited

As far Functionality is concerned.
1.Servlet is used for writing Control logic
2.Session bean is used for handling Business logic.
3.Entity bean represents data (It maps to a record in database)
