Here's how I delete a cookie:

Cookie cart = new Cookie( "CART", null );
cart.setMaxAge( 0 );
resp.addCookie( cart );

Also, your wording concerns me. You say you still see the cookie
"in the cookie file". Perhaps your browser internally caches the
cookie jar and only writes it out when exiting?

HOW WE'RE DELETING COOKIES:
protected void deleteCookie(String cookieName)
{ String cookieDomain =
CTPropertiesManager.getProperty("site.properties",

"site.cookie.domain");

try
{ //get all cookies
Cookie cookies[] = request.getCookies();

Cookie ctCookie=null;
if (cookies !=null)
{ for(int i=0; i
{ ctCookie=cookies[i];
if (ctCookie.getName().trim().equals(cookieName))
{ if ( cookieDomain != null )
{ ctCookie.setDomain(cookieDomain);
}

ctCookie.setPath("/ct");
ctCookie.setMaxAge(0);
response.addCookie(ctCookie);
} }//end for
}//end if cookie
}//end try
catch(Exception e){
CTLogManager.log(e);
} }//end deleteCookie()
