Sessions are not needed. Many e-commerce apps do just fine without them. They can, however, greatly simplify the development of an e-commerce app. I've yet to see a Servlet/JSP book that doesn't cover sessions and their use. If you search this or the Servlets forum with the keyword "book", you will find plenty of recommendations.
