title: Stateful EJBs in web application?
body: <p>I never used stateful EJBs. 
  I understand that a stateful EJB can be useful with a java client.</p>
  
  <p>But i wonder: in which case to use them on a web application?  And how?
  Should we put these stateful beans in Session (because of stateless http)?</p>
  
  <p>Is it a good practice? 
  (without debating too much about stateful vs stateless)</p>
