@WebServlet("/fail")
public class FailView extends HttpServlet {
	
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		process(request,response);
	}
	
    
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

	}
	
    
	protected void process(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		
//		client 브라우저에 "무효한 id입니다" 출력
		response.setContentType("text/html;charset=UTF-8");
		PrintWriter out = response.getWriter();
		out.println("무효한 id입니다");
	}
}

login.html에서 id : tester11로 입력하면 (tester제외 다른 id는 fail)

무효한 id입니다 출력
