title: how to fix this, JavaScript Error : document.forms. is null not an Object
body: <p>in my jsp page, I am getting script error.  <strong>error message is : document.forms[0] is null not an object.</strong>when i click  to SignOut . sign Out works fine and it is redirect to default.jsp. but my default.jsp doesn't show anything just a blank page. I checked view Source of  default.jsp page.The whole page is not loaded. it has loaded only till <strong>1st line of body tag.</strong> Below is the code for <strong>default.jsp .</strong></p>
  
  <pre><code> &lt;! doctype html&gt;
   &lt;html language="en"&gt;
   &lt;%@  page language="java" contentType="text/html" %&gt;
  &lt;%@ session ="false" %&gt;
  
  &lt;head&gt;
  &lt;script type="text/javascript"&gt;
  
  function closeWarning(){
  
          document.forms[0].reset();
  
   }
       &lt;/script&gt;
  &lt;/head&gt;
  
   &lt;body onLoad="closeWarning();" class="page-design"&gt;// page loaded till here
   &lt;jsp:include flush="true" page="/myCart/header.jsp"/&gt;
  //---other component of body----
   &lt;/body&gt;
  </code></pre>
