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

import student.dao.UserInfo;

public class LoginAction extends HttpServlet {
	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		request.setCharacterEncoding("GBK");
		String userName=request.getParameter("userName");
		String pwd=request.getParameter("pwd");
		String type=request.getParameter("type");
		UserInfo user=new UserInfo();
		user.setUserName(userName);
		user.setType(type);
		String URL="/servlet/GetListAction";
		if(userName.equals(pwd)){
			request.getSession().setAttribute("user", user);
			URL="/servlet/GetListAction";
		}else{
			URL="/login/login.jsp";
		}
		getServletConfig().getServletContext().getRequestDispatcher(URL).forward(request,response);
	}

	public void doPost(HttpServletRequest request, HttpServletResponse response)
