Setting Cookie

[Jigar Naik]

I have created a small application to create and set cookie. My servlet code is bellow.

   
resp.setContentType("text/html");
String name = req.getParameter("param1");
Cookie cookie = new Cookie("param1",name);
cookie.setMaxAge(30*60);
resp.addCookie(cookie);
System.out.println("param1 : " + name);
System.out.println("getPath() : " + cookie.getPath());
resp.sendRedirect("/WTS/jsp/cookieTest.jsp");

can anybody tell me what will this code do ?
and if it is creating cookie than where can i see my cookie ?
what will be the default location of my cookie ?
how cn i set the cookie location ?
I want to set the cookie at client end.

This code creates a cookie named 'param1', and map its value to whatever the value of the query parameter 'param1' is, and its expiry value is 1800 seconds.

developers don't need to worry about the location, the cookie is by default stored on client-end, where the location is where your browser store your temporary internet files.

Hope that helps.

but how do i retrive the name value pairs stored in the cookie ?

[Jigar Naik]

and what does this function doing

 
cookie.getPath(); 

I had written it to know the location of cookie at client end.

Java Doc would be your first place to know about it..Cookie.getPath

you can get name value pairs by using following code

 
  Cookie [] cookies = request.getkookies(); 
 

loop through cookies array using a for or while loop

  
   for(int i=0;i<cookies.length;i++)
   {
 
      if(cookies[i].getName().equalsIgnoreCase("cookiename")
        System.out.println("cookie value is:"+ cookies[i].getValue());
   }
