The file login7.jsp:
jsp:useBean id=FormBean class=userinfo.FormBean/
jsp:setProperty name=FormBean property=*/
HTML
HEAD
TITLEForm Example/TITLE
/HEAD
BODY BGCOLOR=#cc
% if (request.getParameter(name)==null
request.getParameter(email) == null) { %
CENTER
H2User Info Request Form /H2
form method=GET action=process2.jsp
P
Your name: input type=text name=name size=27
p
Your email: input type=text name=email size=27
P
input type=submit value=Process
/FORM
/CENTER
% } else { %
P
BYou have provided the following info/B:
P
BName/B: jsp:getProperty name=FormBean property=name/
P
BEmail/B: jsp:getProperty name=FormBean property=email/
% } %
/BODY
/HTML
and the file FormBean.java:
package userinfo;
import java.io.*;
public class FormBean implements Serializable
private String name;
private String email;
public FormBean()
name = null;
email = null;
