public void visitListener(WebAppContext context, Descriptor descriptor, XmlParser.Node node)
{
  String className = node.getString("listener-class", false, true);
  EventListener listener = null;
  try
  {
    if (className != null && className.length()> 0)
    {
      //Servlet Spec 3.0 p 74
      //Duplicate listener declarations don't result in duplicate listener instances
      for (ListenerHolder holder : context.getServletHandler().getListeners())
      {
        if (holder.getClassName().equals(className))
          return;
      }
      ((WebDescriptor)descriptor).addClassName(className);
      
      ListenerHolder h = context.getServletHandler().newListenerHolder(new Source (Source.Origin.DESCRIPTOR, descriptor.getResource().toString()));
      h.setClassName(className);
      context.getServletHandler().addListener(h);
      context.getMetaData().setOrigin(className+".listener", descriptor);
    }
  }
  catch (Exception e)
  {
    LOG.warn("Could not instantiate listener " + className, e);
    return;
  }
}
