title: How to get parameters from URL in Liferay portlet?
body: <p>I'm using jsp of out-of-box portlet like feed.jspf in Liferay 6:</p>
  
  <pre><code>String articleId =null;
  HttpServletRequest httpReq = PortalUtil.getOriginalServletRequest(PortalUtil.getHttpServletRequest(renderRequest));
  articleId = httpReq.getParameter("articleId");
  </code></pre>
  
  <p>It is giving a null value whether in custom portlet or in .jsp files, but it should have a value.</p>
