java script error help please

When I run the following jsp to automaticcally refresh every 10 seconds i'm geting javascript error that object is null on line document.refreshForm.submit(). can you please help on sloving the issue.
I double checked the stuts file and action and form path has been defined.

<%@ page import='java.util.*' %>

<%@ page import='presentation.action.RefreshTimer' %>

<%@page import='presentation.action.RefreshAction'%>

<%@page import='presentation.form.RefreshForm'%>

<script language="javascript" >

var temp = window.setInterval('submitPage()',10*1000);

function submitPage(){

alert("before count submit");

document.refreshForm.submit();

var xyz = <%=application.getAttribute("counter")%>

alert("New Request is " + xyz);

}

</script>

<html:form action="/refresh.do" method="post" onsubmit ="submitPage()">

</html:form>

Moved to the HTML/Javascript forum.

Where is refreshForm defined?

Bear,
RefreshForm is deifned in the struts file of the action path(refresh.do) and form bean
<form bean name ="refreshForm" path="presentation.form.RefreshForm">

That is not in your above example.

The form name is defined in sturts config file of that particluar action which is refresh.do

Even if i declare the form name as myform when i call the jsp page it gives me an error that document.myForm is not an object or is null. How can i resolve this.

In order for the reference document.refreshForm to resolve to an actual element, there has to be a form element with that name defined on the page. Until there is, you are going to continue to get the error.

What are you trying to accomplish by submitting a form that does not exist on the page?

Bear,

I defined on the form page as follows:
<html:form name ="refreshForm" action="/refresh.do" method="post" type ="presentation.form.RefreshForm">

This does not work so I created a hidden element but did not work either.
<input type="hidden" name="refreshForm" value="count" />

I want to submit the form to the server to get new values from database.
how can i submit this form from jsp page to the server without using submit buttons.

You already posted the code above to do it.

This does not work

This is not useful information that will help diagnose the problem. How does it not work?

This does not work so I created a hidden element but did not work either.

Stabbing in the dark is rarely effective.

document.refreshForm.submit();

<input type="hidden" name="refreshForm" value="count" />

As Bear pointed out, refreshForm needs to be a form, you can't define it as an input element.
