title: Add remove() method to DAO
body: <p>I am following <a href="http://www.developer.com/java/web/integrate-objectdb-into-your-jpa-based-java-web-app.html" rel="nofollow">this tutorial</a>, which is the easiest Java EE web app using JPA I found on the net after weeks of searching, and I'd like to add a remove method to the DAO but I don't know exactly how to do it.</p>
  
  <p>Here the code I've added to the DAO class:</p>
  
  <pre><code>Player player = em.find(Player.class);
  em.remove(player);
  </code></pre>
  
  <p>Is it possible to add CRUD functionality? I want keep the code as simple as possible.</p>
