Hi ,

  Follow the simple rule.

1. Use session bean to do some actions like bookTicket, cancelTicket, checkForAvailablity etc.

2. Whenever your going to represent something from database use entity bean. Like Customar, Airplan , Seat etc.

Session bean has business logic and database operation methods.

Entity bean's one feature is to make your application database independent. means if you change database,tables u need not to see code written in your session bean u just need to edit very few line in you entity DD files.
