Re: Writing cookie in jsp

Hi Surya,

As you know, javascript is executed on client side, against JSP(or Servlet) on server side.

Then, there is no way to add the value of a textfield to the cookie using JSP in one session.

But if you decide to use javascript to add the value to the cookie, you can.

As a reference, you can write JSP code that generates javascript code in JSP 1.0 spec.

ex)

<%@ page language=javascript %>

... javascript code ...

I recommend for you to post the textfield value(using form/action) to JSP that handles the value.

ex)

In page1.jsp

</form>

In writecookie.jsp

String value1 = request.getParameter("name1"); // getting the value of textfield

Cookie cookie = new Cookie("name1", value1); // adding cookie

cookie.setPath("/");

response.addCookie(cookie);

I hope it will help you.

In JSP,

<%

// Adding Cookie(name1 = value1)

Cookie cookie = new Cookie("name1", "value1");

cookie.setPath("/");

response.addCookie(cookie);

// Getting Cookie(name1)

Cookie[] cookies = request.getCookies();
String value = "";

if (cookies != null)

{

    for (int i=0 ; i<cookies.length ; i++)

    {
        if (cookies[i].getName().equals("name1"))
        {
             value = cookies[i].getValue();
             break;

        }
   }
}
return value;

%>

I don't have a code snippet available this second, but you can read/write cookies using the request/response streams. Look at the API for the Cookie class...

Until now, I have always used javascript to write cookies.  Does anyone have a code snippets (or suggestions on how) to write and delete cookies using JSP and/or a javabean?
