请高手指教servlet
我的jsp页面接收不了servlet的发来的数据
不知道哪出问题了
以下是
userModify.jsp
<%@ page language="java" import="java.util.*,zls.market.entity.smUser" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
