title: how to set a PrimeFaces theme?
body: <p>I'm trying to get my PrimeFaces (v2.1) app to use a different theme.</p>
  
  <p>I downloaded vader-1.0.0.jar and put it in my WEB-INF/lib folder.</p>
  
  <p>I added the following to my web.xml:</p>
  
  <pre><code>&lt;context-param&gt;   
    &lt;param-name&gt;primefaces.THEME&lt;/param-name&gt;
    &lt;param-value&gt;vader&lt;/param-value&gt; 
  &lt;/context-param&gt;
  </code></pre>
  
  <p>But when I run the app, the theme does not change.</p>
  
  <p>Is there something else I'm missing?</p>
