JSTL compare string

hi, :p

i am trying to achieve a registration page in JSP. i am using tag library to do this.

c tag library and Sql tag library.

<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<c:if test="${param.submitted}">
	<c:if test="${empty param.name}" var="noname" />
	<c:if test="${empty param.pw}" var="nopw" />
	<c:if test="${empty param.cpw}" var="nocpw" />
<c:if
test="${not (noname or nopw or nocpw or requestScope.takenName)}">


<c:set value="${param.name}" var="name" scope="request" />
<c:set value="${param.pw}" var="pw" scope="request" />
<c:set value="${param.cpw}" var="cpw" scope="request" />




<jsp:forward page="postregister.jsp"/>



	</c:if>
		</c:if>

<html>
<head> 
</head>
<body bgcolor="CFECEC" >



<form method="post" name="frmRegister">
<input type="hidden" name="submitted" value="true"/>






<script type="text/javascript">

<!--

	function add_onclick() {
		
		var TRUE = new Boolean("True")
		var FALSE = new Boolean("False")
		
		blnError = FALSE
		strError = "The following problems were found in your registration form: \n\n"
		
		
			
		if (frmRegister.name.value == "")
			{
				blnError = TRUE
				strError = strError + " - You must provide a Login Name\n"
			};
			
		if (frmRegister.pw.value == "")
			{
				blnError = TRUE
				strError = strError + " - You must provide a Password\n"
			};
		if (frmRegister.cpw.value == "")
			{
				blnError = TRUE
				strError = strError + " - You must confirm your Password\n"
			};
			
			
		if (frmRegister.pw.value != frmRegister.cpw.value)
			{
				blnError = TRUE
				strError = strError + " - Your Password does not match\n"
			};
			
		if (blnError == TRUE)
			{
				strError = strError + "\nPlease correct these mistakes and try again."
				alert(strError)				
			}
		else
			{
				frmRegister.submit()
			};				
		
	}
