我的源码是：
<%@ page language="java" contentType="text/vnd.wap.wml;charset=GB2312" %>
<%@page import="com.icbc.cc.common.*,com.icbc.cc.app.base.*,com.icbc.cc.app.object.*"%>
<%
ValuePackage outPkg=(ValuePackage)request.getAttribute("pkg");
System.out.println("In menu_dljf.jsp");
String kdmt= (String)session.getAttribute("kdmt");
System.out.println("In menu_dljf.jsp kdmt==:"+kdmt);
String firstshow = (String)session.getAttribute("firstshow");
String TermID = (String)session.getAttribute("TermID");
System.out.println("In menu_dljf.jsp firstshow==:"+firstshow);
System.out.println("In menu_dljf.jsp TermID==:"+TermID);
%>

<%

}

为什么firstshow的值在转到后台servlet和下一个页面时，通过
String firstshow = (String)session.getAttribute("firstshow");
取到的firstshow的值为null呢？
请各位帮忙。 |
