String passward= "";
Cookie[] Cookies=request.getcookies ();
if (cookies!=null) {
for (int i=0;i<cookies.length;i++) {
Cookie cookie = cookies[i];
if (Cookie.getname (). Equalsignorecase ("OA")) {

If ("". Equals (Savecookie)) {
    cookie cookie = new Cookie ("OA", null);
    cookie.setmaxage (0);
    Cookie.setpath ("/");
    Response.addcookie (cookie);
} else if (Savecookie.equals ("save") {
    cookie cookie = new Cookie ("OA", username + "-" + Pass Word);
    Cookie.setmaxage (24 * 60 * 60 * 365);//No time set, unable to save local cookie
    Cookie.setpath ("/");
    Response.addcookie (cookie);
