import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class AjaxController extends HttpServlet {
    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
        try {
            switch(request.getServletPath()){
                case "/Login" :  {
                    String email = request.getParameter("email").trim();
                    String senha = request.getParameter("senha").trim();
                    UsuarioDAO usudao = new UsuarioDAO();
                    if(usudao.login(email, senha)){
                        response.setStatus(response.SC_MOVED_TEMPORARILY);
                        response.setHeader("location", "http://localhost:8080/dbdfacu2/dashboard.jsp");
                    }
                }
                break;
                case "/Register" : {
                    String nome = request.getParameter("nome").trim();
                    String email = request.getParameter("email").trim();
                    String senha = request.getParameter("senha").trim();
                    UsuarioDAO usudao = new UsuarioDAO();
                    try (PrintWriter out = response.getWriter()) {
                        out.println(usudao.inserir(nome, email, senha));
                    }
                }
                break;
            }
        } catch (Exception erro) {
            throw new RuntimeException("ERRO Ajax" + erro);
        }
    }
}

使用resp.sendRedirect相反

resp.sendRedirect(req.getContextPath() + "/redirected");

We use original response object to redirect this request to another URL
