import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class ConfirmServlet extends HttpServlet {

	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		service(request, response);
	}

	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		service(request, response);
	}

	public void service(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {

		//得到用户id
		String userid = request.getParameter("USERID");
		
		if (userid.equals("Bush")) {
			response.getWriter().println("1");
		} else {
			response.getWriter().println("0");
		}
	}
