Stateful beans and Stateless beans in Spring context

Question

I am reading spring through its official documentation and at one place I came to a line that uses prototype scope for all stateful beans while singleton for stateless beans

Answer 1

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.

Answer 2

It totally depends on the implementation. See tomee for example http://tomee.apache.org/statelesscontainer-config.html . You'll have to check in your server docs
