I created a web application that edit a database…
I would like to know how I add or redirect the page after clicking on submit.
Sorry i’m still learning…
Currently Im using “usebean” to insert the content of the form to the database. I would like to know if how to redirect the page after the enter all info in the fields then click submit..
Thanks
here’s the code:
<%@ page language="Java" import="java.sql.*" %>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<html>
<head><title>CSN Survey</title></head>
<body bgcolor="#ffffff">
<div>
<img id="title" src="images/CSN.gif" width="243" height="27" alt="CSN"/>
<img id="logo" src="images/tr_logo_40.gif" width="178" height="40" alt="tr_logo_40"/>
</div>

It will be good to use MVC pattern, you can move business logic
into controller and then send redirect
