JSP form validation qestion

Hi all,

I want to do some form validation using JSP.
So I have a html page that posts to validate.jsp. Validate.jsp uses a bean for validation and has a scope of session. if it is valid then it sendRedirect to sucess or if it fails then it sendRedirect to signup2.jsp. i want signup2.jsp to display the error and take the fields that are valid and populate it on signup2.jsp so that the user does not have to retype the stuff. I have this partitally working. The part that does not work is when in the html file, if there is an error it goes to signup2.jsp like it is suppose to but when the user enter the correct information and repost back to validate.jsp it seems like the new information does not get picked up. help. i tried using request as the scope and that did not work. code sniplet below.

thanks

validate.jsp

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

<jsp:useBean id="vf" class="com.tdw.webmodule.beans.SignUpBean" scope="session" />
<jsp:setProperty name="vf" property="*"/>

<%
if(vf.isValid()) {

//successful
response.sendRedirect("/servlet/members/signup2.jsp");
} else {
//failed
response.sendRedirect("/servlet/members/signUpRetry.jsp");
}
%>

signup2.jsp

<jsp:useBean id="vf" class="com.tdw.webmodule.beans.SignUpBean" scope="session" />
<%! String referral_id; %>
<%
if (request.getParameter("referral")!=null) {
referral_id=request.getParameter("referral");
}

%>

<form name="signup" method="post" action="/servlet/validate.jsp">
