title: Playframework 2.1 doesn't find javax.persistence and play.db
body: <p>I have a problem with the Scala tutorial for creating an Entity with the play framework (Version 2.1). I'm trying to do:</p>
  
  <pre><code>import java.util._
  import javax.persistence._
  import play.db.jpa._
  </code></pre>
  
  <p>But when I compile it tells me that javax.persistence dosen't exist and play.db neither.</p>
  
  <p>I suppose it's a problem of version because it seems to me that the actual yabe-tutorial is a bit old. Do you know any website who has good explanations and examples?</p>
  
  <p>Thanks for your help!</p>
