用到两个jsp页面指令:
isErrorPage=true/false ( true 则页面可以使用exception,false不可用)
errorPage 默认忽略,例子: errorPage="error/error.jsp"
代码如下:
error.jsp 异常处理页:
<%@page contentType="text/html;charset=gbk" isErrorPage="true"%>
<HTML>
<HEAD>
<link rel="stylesheet" type="text/css" href="/style/sound.css">
</HEAD>
<body bgcolor=gray topmargin="10" leftmargin="0" id="TheBody">
<table border="0" bgcolor=#e0e0e0 align="center" cellspacing="0" style="BORDER-RIGHT:gray 2px solid; BORDER-TOP:white 2px solid; BORDER-LEFT:white 2px solid; BORDER-BOTTOM:gray 2px solid" width="407">
<tr>
<td width=10px></td>
<td><%=exception.getMessage()%></td>
</tr>
</table>
</body>
</HTML>
<HTML>
<HEAD>
<link rel="stylesheet" type="text/css" href="/style/sound.css">
</HEAD>
<body bgcolor=gray topmargin="10" leftmargin="0" id="TheBody">
<table border="0" bgcolor=#e0e0e0 align="center" cellspacing="0" style="BORDER-RIGHT:gray 2px solid; BORDER-TOP:white 2px solid; BORDER-LEFT:white 2px solid; BORDER-BOTTOM:gray 2px solid" width="407">
<tr>
<td width=10px></td>
<td><%=exception.getMessage()%></td>
</tr>
</table>
</body>
</HTML>
我们来测试一下.制造一个异常:
testerr.jsp
<%@ page contentType="text/html;charset=GBK"%>
<%@ page errorPage="error.jsp"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
</head>
<body>
<!--s 没有定义,所以会出错-->
<%=s%>
</body>
</html>
<%@ page errorPage="error.jsp"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
