title: forward from doPost() to doGet()
body: <p>I am making a servlet for attendance. So in the <code>doGet()</code> method all the front end is displayed and if any error is generated ; i.e., something is left blank then the <code>doPost()</code> method should call the <code>doGet()</code> again for completing the blank spaces.</p>
  
  <p>How can I call <code>doGet()</code> method from the same servlet's <code>doPost()</code>?</p>
