hello guys:I run the following files that belong to the lab 4008:
productos.jsp:
<%@ taglib prefix="tags" tagdir="/WEB-INF/tags" %>
<html>
<head>
<title>JSP 2.0 Examples - Display Products Tag File</title>
</head>
<body>
<h1>JSP 2.0 Examples - Display Products Tag File</h1>
<hr>
<p>This JSP page invokes a tag file that displays a listing of
products. The custom tag accepts two fragments that enable
customization of appearance. One for when the product is on sale
and one for normal price.</p>
<p>The tag is invoked twice, using different styles</p>
<hr>
<h2>Products</h2>
<tags:displayProducts>
<jsp:attribute name="normalPrice">
Item: ${name}<br/>
Price: ${price}
</jsp:attribute>
<jsp:attribute name="onSale">
Item: ${name}<br/>
<font color="red"><strike>Was: ${origPrice}</strike></font><br/>
<b>Now: ${salePrice}</b>
</jsp:attribute>
<jsp:attribute name="anotherJSPFragment">
This is the item: <font color="red"> ${name} </font><br/>
<font color="blue"><strike>Was: ${origPrice}</strike></font><br/>
<b>The price now is: ${salePrice}</b>
</jsp:attribute>
</tags:displayProducts>
<hr>
<h2>Products (Same tag, alternate style)</h2>
<tags:displayProducts>
<jsp:attribute name="normalPrice">
<b>${name}</b> @ ${price} ea.
</jsp:attribute>
<jsp:attribute name="onSale">
<b>${name}</b> @ ${salePrice} ea. (was: ${origPrice})
</jsp:attribute>
</tags:displayProducts>
<hr>
<h2>Products (Same tag, the 3rd style)</h2>
<tags:displayProducts>
<jsp:attribute name="normalPrice">
My own display format: ${name} ${price} per item
</jsp:attribute>
<jsp:attribute name="onSale">
My own display format ${name} ${salePrice} per item
(Yesterday it was: ${origPrice})
</jsp:attribute>
</tags:displayProducts>
</body>
</html>
I added the following two sentences to the displayproducts.tag:
<%@ attribute name="another JSPFragment" fragment="true" %>
*<jsp:invoke fragment="anotherJSPFragment"/>*i obtained this wrong after
run:
