Hi, can anyone help me w/ this:
1. Created the following custom tag:
<%@ attribute name="normalPrice" fragment="true" %>
<%@ variable fragment="normalPrice" name-given="name" %>
<%@ variable fragment="normalPrice" name-given="price" %>
<%@ attribute name="onSale" fragment="true" %>
<%@ variable fragment="onSale" name-given="name" %>
<%@ variable fragment="onSale" name-given="origPrice" %>
<%@ variable fragment="onSale" name-given="salePrice" %>
<table border="1">
<tr>
<td>
<jsp:invoke fragment="normalPrice">
<jsp:param name="name" value="Hand-held Color PDA" />
<jsp:param name="price" value="$298.86" />
</jsp:invoke>
</td>
<td>
<jsp:invoke fragment="onSale">
<jsp:param name="name" value="4-Pack 150 Watt Light Bulbs" />
<jsp:param name="origPrice" value="$2.98" />
<jsp:param name="salePrice" value="$2.32" />
</jsp:invoke>
</td>
<td>
<jsp:invoke fragment="normalPrice">
<jsp:param name="name" value="Digital Cellular Phone" />
<jsp:param name="price" value="$68.74"/>
</jsp:invoke>
</td>
<td>
<jsp:invoke fragment="normalPrice">
<jsp:param name="name" value="baby Grand Piano" />
<jsp:param name="price" value="$10,800.00" />
</jsp:invoke>
</td>
<td>
<jsp:invoke fragment="onSale">
<jsp:param name="name" value="Luxury Car w/ Leather Seats" />
<jsp:param name="origPrice" value="$23,980.00" />
<jsp:param name="salePrice" value="$21,070.00" />
</jsp:invoke>
</td>
</tr>
</table>
2. Created the following JSP:
<%@ taglib prefix="tags" tagdir="/WEB-INF/tags" %>
<html>
<head>
<title>Shopping: A Simple Tag Example</title>
</head>
<body>
<h1>ABC Store: New Year Sale</h1>
<h2>$$ Weekend Prices...Hurry$$</h2>
<tags:catalog>
<jsp:attribute name="normalPrice">
${name}<br>
${price}
</jsp:attribute>
<jsp:attribute name="onSale">
Item: ${name}<br>
<strike>Was: ${origPrice}</strike><br>
<b>Now: ${salePrice}</b>
</jsp:attribute>
</tags:catalog>
</body>
</html>
3. Got the following error when trying to view the page:
