If I click on a tab in our application [intern is a JSP page] I et an error saying " [ServletException in :/WEB-INF/pages/main/main.jsp] null' ".But in another instance the same jsp page doesn't give any error ,the page content will b displayed properly.

I wanted to know what all the reasons to cause this exception.

I hav also removed all th comments written in th jsp page .

Following is th JSP page code:

<%@ taglib uri="/tag/struts-html" prefix="html" %>
<%@ taglib uri="/tag/struts-logic" prefix="logic" %>
<%@ taglib uri="/tag/struts-bean" prefix="bean" %>
<%@ taglib uri="/tag/exxor" prefix="exxor" %>

<script language="javascript">
function submitSearch(id)
{
	document.searchResultSubmit.cancelSearch.value="false";
	document.searchResultSubmit.ID.value=id;
	document.searchResultSubmit.submit();
}
function validateSearch()
{
	if (document.searchSubmit.SEARCHVALUE.value.length < 2)
	{
		alert("Please enter atleast two characters for search");
		document.searchSubmit.SEARCHVALUE.focus();
		return false;
	}
	if (checkWildChar("searchSubmit", "SEARCHVALUE") == false) return false;
	return true;	
}
function cancelSearch()
{
	document.searchResultSubmit.cancelSearch.value="true";
	document.searchResultSubmit.submit();
}
</script>
<div align="center">
