Stateful beans and Stateless beans in Spring context

From spring perspective

• stateless beans: beans that are singleton and are initialized only once. The only state they have is a shared state. These beans are created while the ApplicationContext is being initialized. The SAME bean instance will be returned/injected during the lifetime of this ApplicationContext.

• stateful beans: beans that can carry state (instance variables). These are created EVERY time an object is required (like using the "new" operator in java).

These are not EJB statfull/stateless session beans.
