title: sendRedirect after time interval avoiding javascript or php
body: <p>How can I do the following</p>
  
  <pre><code>response.sendRedirect("index.jsp");
  </code></pre>
  
  <p>after a certain time interval from another jsp without using javascript or php?</p>
  
  <p>The idea is to show an error in a "error_page.jsp" and then after some time automatically redirect the user to the index page. Thanks in advance.</p>
