title: how should I get root folder path in jsp page
body: <p>I want to retrieve root path of webapplication, then I want to append link to root path.
  I tried request.context but it returns "http://localhost:8080/webapp/web-inf".</p>
  
  <p>For example my root folder path is </p>
  
  <pre><code>path  =  http://localhost:8080/webapp/
  </code></pre>
  
  <p>and I want to append remaining link to this path</p>
  
  <pre><code>helpPath= /help/page/help.htm
  
  
  &lt;a  href="${path} + ${helpPath}" target="_blank"&gt;name&lt;/a&gt;
  </code></pre>
  
  <p>Any help or pointer really appreciated.</p>
