- 放在WebRoot目录下jsp文件中引入java代码如下:
<%@ page language="java"contentType="text/html; charset=ISO-8859-1"

</head>
<body>
<%----%>
<%
inta=10;
out.println(a/0);
%>
</body>
</html>
2.在WebRoot文件下新建一个error文件夹,之后在error文件夹下新建一个error.jsp文件,代码如下:
<%@ page language="java"contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type"content="text/html; charset=ISO-8859-1">
<title>error</title>
</head>
<body>
算术运输错误!
</body>
</html>
3.web.xml配置文件如下:
<?xml version="1.0"encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

<display-name></display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!--程序出错跳转到error文件中的error.jsp页面-->
<error-page>
<exception-type>java.lang.ArithmeticException</exception-type>
<location>/error/error.jsp</location>
</error-page>
</web-app>
4.程序运行出错会跳到error.jsp页面,输出:算术运输错误!
