JSP output affected with cookievalue cookie.getValue() function

Question

i need to output from a jsp
fquid=uid@domain
authtype=plaintext
this is the format expected by a calling url.
uid is dynamic
case 1: if i set
String uid="xyz";
the calling url to this jsp behaves perfect. all it matters at this point is that the calling jsp needs output in the above format.
here is the code that works.
<%
out.println( "fquid=xyz@domain\n");
out.println( "authtype=plaintext\n");
%>
case 2:
my job is to make this jsp dynamic. i need to grab the uid from a cookie and output the exact same strings. but this one bombs meaning the calling jsp does not behave correctly.
here is the code i haveth:
<%
String cookieName = "cookiename";
Cookie cookies [] = request.getCookies ();
Cookie myCookie = null;
String cval = null;
if (cookies != null)
for (int i = 0; i < cookies.length; i++)
if (cookies .getName().equals (cookieName))
myCookie = cookies[i];
// out.println( i + "," + myCookie.getValue() + "<BR>");
cval=myCookie.getValue();
break;
String uid=myCookie.getValue();
out.print( "fquid=" + uid + "@domain\n");
out.print( "authtype=plaintext\n");
%>
the moment i introduce myCookie.getValue() function into the code the calling url fails. the output of the both the snippets is same.
what is the problem here?
thanks

Answer 1

Did you even set the Cookie? You need to set it first in order to get it.
To set a cookie
1. Create a new Cookie object and set the name and value in it's constructor.
2. Then add the Cookie into the HTTP Response
3. Call the above code from a URL
4. Look in Browser's cache to verify if the Cookie was written
Also check if Cookies are disabled in the browser.
