web.xml

<error-page>
<error-code>404</error-code>
<location>/building.jsp</location>
</error-page>

<error-page>
<error-code>500</error-code>
<location>/error.jsp</location>
</error-page>

JSP頁面的關(guān)鍵在于

1 isErrorPage="true"

2 response.setStatus(HttpServletResponse.SC_OK);

building.jsp

<%@ page language="java" contentType="text/html; charset=GBK" isErrorPage="true" pageEncoding="GBK"%>
<%response.setStatus(HttpServletResponse.SC_OK);

 %>
<%
/**
* 本頁面是在客戶查找的頁面無法找到的情況下調(diào)用的
*/
response.setStatus(HttpServletResponse.SC_OK);
%>
<body>
正在制作... <a href="javascript:history.go(-1)">返回</a>
 
也可能頁面連接更改了,，請按 F5 鍵刷新整個頁面看看,，特別是菜單！

</body>

error.jsp

<%@ page language="java" contentType="text/html; charset=GBK" isErrorPage="true" pageEncoding="GBK"%>
<%@ page import="java.io.*,java.util.*"%>
<%response.setStatus(HttpServletResponse.SC_OK);

 %>
<body>
程序發(fā)生了錯誤,，有可能該頁面正在調(diào)試或者是設(shè)計上的缺陷. 
你可以選擇 <a href=<%=request.getContextPath()+"/forum/new.jsp" %>>反饋</a>
提醒我... 或者 <a href="javascript:history.go(-1)">返回上一頁</a>
