If you need to maintain state, then stateful session bean are available.

Stateless beans are a lightweight version of stateful beans. These stateless beans are usually more appropriate than stateful beans.

Stateless session beans are pooled, and when needed, any instance can be pulled from the pool, as they are identical. If they had conversational state with the client, not each instance would be identical.

Use stateful session beans if you need to maintain state. Maybe even just the HttpSession if you are developing a Servlet/JSP application.
