    Default DynaValidatorForm isn't working

    Hi,

    When I enter an invalid login the page doesn't display error messages.
    These are my pages.



    LOGIN.JSP

    Java Code: 
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<&#37;@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<html:html>
<head>

<%@ page
language="java"
contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"
%>
<META name="GENERATOR" content="IBM Software Development Platform">

.copy{

}
</style>
</head>

    <formset>
<form name="LoginForm">

    Default


    Try this----

    first of all make validate=true
    write onsumit=" return validateLoginForm(this);" in your form tag
    write <html:javascript formName="LoginForm" /> in your jsp before </html:form> tag

    Having include above things, I think your form should work..
