title: Difference between Java EE 7 and Java EE 6
body: <p>What are the main differences between Java EE 7 and Java EE 6 ?</p>
  
  <p>If you would have to explain to another fellow developer the main differences
  how would you do that ?</p>
  
  <p>As far as the question goes, I was really interested not in the new added technologies, but for the already present ones.</p>
  
  <p>A quick overview would be most than enough for what I'm asking.</p>
  
  <p>To add a further question I'd love to know what major improvements have been added to 
  JAX-WS, JAX-RS and JSF, Is still a Hero task to develop services with Java EE and not rely
  on external frameworks as Spring for example ?</p>
