java(자바)에서 alert띄우기(java.lang.IllegalStateException: Cannot call sendRedirect() after the response has been committed)

1.방법

if("NG"=="NG"){ response.setContentType("text/html; charset=UTF-8"); PrintWriter out = response.getWriter(); out.println("alert('엑셀파일을 확인해주세요.'); history.go(-1);"); out.flush(); response.flushBuffer(); out.close(); }
