Yeah, I think method signature is correct. Following is my method.

---------------------------------------------------------------------
public static String checkAccess(HttpServletRequest request,HttpServletResponse response){
                        Security security = (Security)request.getAttribute("security");
                        String key = "_EVENT_MESSAGE_";
                        if (security.hasPermission("LEARN_VIEW", request.getSession()))
                        {
                        request.setAttribute(key, "You have access!");
                        }
                        else {
                        request.setAttribute(key, "You DO NOT have access! You are denied!");
                        }
                        return "success";
                        }
---------------------------------------------------------------------

Is the method signature correct? i.e. does it look like this:
public static String checkAccess(HttpServletRequest request,  
HttpServletResponse response) {
