Example Demonstration

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
<title>c:catch Tag Example</title>
</head>
<body>

&lt;c:catch var ="catchException">
   <% int x = 5/0;%>
</c:catch>

&lt;c:if test = "${catchException != null}">
   <p>The exception is : ${catchException} <br />
