Here’s a simple Cookie example in Servlet
Java Source
package com.mkyong;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class ServletDemo extends HttpServlet{
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException{
response.setContentType("text/html");
PrintWriter pw = response.getWriter();
Cookie cookie = new Cookie("url","mkyong dot com");
cookie.setMaxAge(60*60); //1 hour
response.addCookie(cookie);
pw.println("Cookies created");
}
}
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>servletdemo</display-name>
<servlet>
<servlet-name>ServletName</servlet-name>
<servlet-class>com.mkyong.ServletDemo</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ServletName</servlet-name>
<url-pattern>/Demo</url-pattern>
</servlet-mapping>
</web-app>
The above example will create a simple Cookie with a name “url” and value “mkyong dot com”, time to live is one hour, and store in client computer.
Run It
