        密码<input type="text" name="passWord"><br>  

        <input type="submit" value="提交">

public void doPost(HttpServletRequest request, HttpServletResponse response)  

            throws ServletException, IOException {  

        String userName = request.getParameter("userName");  

        String passWord = request.getParameter("passWord");  

        response.getWriter().println("userName --->"+userName);  

        response.getWriter().println("passWord---->"+passWord);
