Hello,
I designed some JSP pages with java classes, But my problem is that when i
run these JSP pages on JWS(Java Web server) then it works fine. But When i
ran these JSP pages on TOMCAT then it give s following error,
==============
The JSP page submit list is as follow,
<%@ include file="../templetes/gen_ects_header.tem" %>
<link rel="stylesheet" type="text/css" href="main.css">
<%@ page import="javax.servlet.http.HttpSession" session="true" %>
<%@ page import="java.util.*,shopcart.*"%>
<form method="GET" action="../jsp/submitlist.jsp">
<font face="verdana, arial" size="2">
<center>
<br>
<table cellpadding="0" cellspacing="0" width="70%">
<tr bgcolor="#1A6E24">
<td>
<font face="verdana, arial" size="4" color="#FFFFFF">
<center><b>Shopping Cart</b></center>
</font>
</td>
</tr>
