title: Accessing Spring beans from servlet filters and tags
body: <p>I can access Spring beans in my Servlets using      </p>
  
  <pre><code>WebApplicationContext springContext = 
      WebApplicationContextUtils.getWebApplicationContext(getServletContext()); 
  </code></pre>
  
  <p>in the Servlet's <code>init</code> method.</p>
  
  <p>I was wondering is there an equivalent of the <code>WebApplicationContext</code> for servlet filters?
  Also, is it possible to access Spring beans in a tag class?</p>
