关于jsp数据提交给本页问题
query.jsp
<%@ page language="java" import="java.util.*,kan.jian.mei.client.*" pageEncoding="GB2312"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<%@ page contentType="text/html; charset=gb2312"%>
<%
request.setCharacterEncoding("gb2312");
%>

<body>
<%
String userName = request.getParameter("userName");
BookInfoClient qp = new BookInfoClient();
String BookInfo = qp.getInfoByName(userName);
out.println(userName);
%>
<form name="bookinfo" action="query.jsp" method="post" onsubmit="return false;">
输入书籍名称：<input type="text" value="<%=userName%>" name="userName"><br><br>
<input type="submit" value="查询">
</form>
<div>
<br><div><%=BookInfo%></div>
</div>
</body>
</html>
我想要实现的功能是输入书籍名称之后点击查询按钮之后div中的bookinfo信息显示出来，可是现在点击根本没有反应，而且bookinfo显示区域一直显示null，我以前貌似解决过类似问题，但是现在好久没用就忘记了，哪位大侠知道帮个忙，十分感谢
