@WebServlet(name = "Servlet2",urlPatterns = "/onee")

public class Servlet2 extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doGet(request, response);
    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        PrintWriter  out = response.getWriter();
        out.print("2333333333");
        String name = request.getParameter("name1");
        out.print(name);
    }
