title: java spring starter question
body: <p>I am looking into Spring and I want to ask the following:<br>
  I see that there is Spring2 and Spring3.<br>
  My question is, should I ignore Spring2, or If I read on Spring2 the concepts are the same in Spring3?<br>
  I ask this, because when starting to look into EJB2 I found out that it is obsolete (replaced completely by EJB3) and I wasted my time.  </p>
  
  <p>Thank you</p>
