title: Jetty 8 standalone doesn't detect jstl taglib jar
body: <p>I have started a simple servlet 3.0 project which contains now a jsp page where I am using the jstl core tags. If I'm starting this with mvn jetty:run I can see the output properly calculated. But if I'm packaging the project as a war and deploy it into a standalone jetty server, it fails for the same page with </p>
  
  <pre><code>PWC6188: The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application
  </code></pre>
  
  <p>I have checked that jstl-1.2.jar is in the war under WEB-INF/lib. What did I miss else?</p>
  
  <p>I am using jetty 8.1.3.v20120416 in maven and the standalone installation.</p>
