This method can be called from handle(String, Request, HttpServletRequest, HttpServletResponse)
when an DispatcherType.ERROR
dispatch
is detected and an error page needs to be generated by calling HttpServletResponse.sendError(int, String)
with the appropriate code and reason,
which are taken from ServletRequest.getAttribute(String)
for RequestDispatcher.ERROR_STATUS_CODE
and RequestDispatcher.ERROR_MESSAGE
