title: Resources to learn EJB
body: <p>I am gonna start learning EJB. I just need your suggestion on picking the version for learning EJB 2.0 or EJB 3.0. Is it good idea to start with EJB 2.0 and migrate to EJB 3.0? If it is, can it be easy to migrate? Actually I am holding Head First EJB book covering version 2.0. Suggest me any other good book, that I can stick to it for complete learning of EJB.</p>
  
  <p>I am very grateful to you if you help me in becoming EJB Guru</p>
