title: javax.el.CompositeELResolver class not found in Tomcat
body: <p>When I am developing a JSF project in Tomcat 7, the server keep arguing this class not found. May I know which jar am I missing?</p>
  
  <pre><code>Caused by: java.lang.ClassNotFoundException: javax.el.CompositeELResolver
  </code></pre>
  
  <p>I have already put this jar in the Tomcat lib folder:</p>
  
  <ol>
  <li>jsf-api-2.0.1.jar</li>
  <li>jsf-impl-2.0.1.jar</li>
  <li>javax.servlet-api-3.0.1.jar</li>
  </ol>
  
  <p>Beside this, I also have <code>servlet-api-2.5.jar</code> and <code>servlet-api.jar</code>, not sure which one is currently using by Tomcat 7.</p>
