Still my problem is unsolved! PLZ help!

Question

hi,
i'm using cookies in my application
1) in file1.jsp i'm setting the cookie as -----
Cookie cook11 = new Cookie("noOfRows","10");
response.addCookie(cook11);
2) in file2.jsp i'm retrieving that value as-----
ServletUtilities is user defined class
ServletUtilities su = new ServletUtilities();
Cookie[] cook = request.getCookies();
String strnoOfRows = su.getCookieValue(cook,"noOfRows","");
3) in file3.jsp i'm reseting the value of cookie as-----
ServletUtilities su = new ServletUtilities();
Cookie[] cook = request.getCookies();
Cookie cook1 = su.getCookie(cook,"noOfRows");
cook1.setValue(strnoOfRows1);
now the problem is after changing the cookie value by running file3 after that if i run file2 and check the cookie value it won't change as setted in file3.
These files are running in browser(IE/Netscape) only .
rather the application is web based.
when i start the application file1 runs then file2, which contains value of cookie same as set in file1...........
i'm providing an opportunity to client to change the cookie value in file3...................
now i want that if user run file2 again further it should show the changed value.
as per someones suggestion
i changed my file3 as...........
ServletUtilities su = new ServletUtilities();
Cookie[] cook = request.getCookies();
Cookie cook1 = su.getCookie(cook,"noOfRows");
cook1.setValue(strnoOfRows1);
response.addCookie(cook1);
BUT SILL MY PROBLEM HAS NOT SOLVED .......................PLZ TELL SOME SOLUTION.

Create a new cookie and overwrite the old cookie instead of attempting to change it's value.
     Cookie cook1 = new Cookie("noOfRows",strnoOfRows1);
     cook1.setPath("/myApp");
     response.addCookie(cook1);
