I have written the code to add a user to the database. The code works when I reload the server. However, when I refresh the page I am expecting the code to be executed again but it does not. Below is the code:
<%@page import="java.sql.*"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Home page</title>
<script language="javascript" type="text/javascript">
</script>
</head>
<body>
<jsp:useBean id="dataFactory" scope="session" class="classes.Functions"/>
<%
response.setHeader("Cache-Control","no-cache");
out.print(dataFactory.getStatus());
out.print(dataFactory.getError());
%>
<form style="text-align:center" name="loginform" action="index.jsp" method="POST">
<img src="banner-02.jpg" width="700" height="150" alt="banner-02"/>
<table>
<tr>
<td>User Name: </td>
<td><input type="text" name="UserName" value="" size="40" /></td>
</tr>
<tr>
<td>Password: </td>
<td><input type="text" name="Password" value="" size="40" /></td>
</tr>
</table>
<input type="reset" value="Clear" name="reset" /><input type="submit" value="Submit" name="submit" />
</form>
</body>
