title: jar file for JPA 2.0
body: <pre><code>import javax.persistence.criteria.CriteriaBuilder;
  import javax.persistence.criteria.CriteriaQuery;
  import javax.persistence.criteria.Root;
  </code></pre>
  
  <p>I've created a JPA project where I try to user the above classes but I'm unable to find what jar I'm missing for them. Please guide me.</p>
