**xirowei** · Oct 27 '07, 05:52 PM

I try to search information from many websites, but what i can found is they only demonstrate the example with ONE ATTRIBUTE in a Cookie only.

What i want is how to set more than 1 attribute in a same cookie?

Below is my code: currently i only can show the username but cannot show the age. How to enable the ShowCookie.jsp able to show both the attribute of "username" and "age" enter by User?

GetValue.jsp

Code:

<%@ page language="java" %>
<html>
<head><title>Get username & age</title></head>
<body bgcolor="cyan">
<table>
<form method="post" action="http://localhost:8080/SetCookie.jsp">
	<tr>
		<td>Enter Your Name:</td>
		<td><input type="text" name="username" length="20" maxlength="20"></td>
	</tr>
	<tr>
		<td>Enter Your Age:</td>
		<td><input type="text" name="age" length="3" maxlength="3"></td>
	</tr>
	<tr>
		<td colspan="2"><center><input type="submit" value="Submit"></center></td>
	</tr>
</form>
</table>
</body>
</html>

SetCookie.jsp

Code:

<%@ page language="java" %>
<%
	String username=request.getParameter("username");
	String age=request.getParameter("age");
	if(username == null) username = "";
	if(age = null) age = "";

	Cookie usernameCookie = new Cookie("username",username);
	usernameCookie.setMaxAge(7*24*60*60);
	response.addCookie(usernameCookie);
	
	Cookie ageCookie = new Cookie("age",age);
	ageCookie.setMaxAge(7*24*60*60);
	response.addCookie(ageCookie);
%>

<html>
<head><title>Set Cookie</title></head>
<body bgcolor="cyan">
<a href="http://localhost:8080/ShowCookie.jsp">Show cookie value</a>
</body>
</html>

ShowCookie.jsp

Code:

<%@ page language="java" %>
<%
	String cookieName = "username";
	String cookieAge = "age";
	
	Cookie cookies [] = request.getCookies();
	Cookie usernameCookie = null;
	Cookie ageCookie = null;
	
	if(cookies != null)
	{
		for(int i=0; i<cookies.length; i++)
		{
			if(cookies [i].getName().equals(cookieName))
			{
				usernameCookie = cookies [i];
				break;
			}
			
			if(cookies [i].getName().equals(cookieAge))
			{
				ageCookie = cookies [i];
				break;
			}
		}
	}
%>

<html>
<head><title>Show Cookie</title></head>
<body bgcolor="cyan">
<%
	if(usernameCookie == null)
	{
		out.println("Hello, World!");
	}
 	else 
 	{
		out.println("Hello, " + usernameCookie.getValue() + "!");
	}
%>

<%
	if(ageCookie == null)
	{
		out.println("You forgot enter your age!");
	}
	else
	{
		out.println("Your age is: " + ageCookie.getValue() + "!");
	}
%>
