Java Reference
In-Depth Information
and is shown in Listing 3-58. This JSP retrieves the list of active products from the servlet
context and displays them.
Listing 3-58.
ProductLoV.jsp
<%@ taglib prefix="c" uri="
http://java.sun.com/jsp/jstl/core"
%>
<%@ taglib prefix="fmt" uri="
http://java.sun.com/jsp/jstl/fmt"

<title>LoV - Product</title>

<body>
<table>
<tr>
<td>Product Id</td>
<td>Product Name</td>

<c:forEach var="productDtl" items="${applicationScope.productDtlList}" >

</c:forEach>

As shown in Listing 3-58, we are using a JSTL-based view helper to retrieve and
present the data stored in application scope.
applicationScope
is an implicit object avail-
able with the JSTL Expression Language, and it gives a handle to the servlet context. In
Listing 3-58, it looks for an attribute with the key
productDtlList
in the servlet context.
To use this semistatic view, you need to slightly alter the configuration, as shown in
Listing 3-59. Note that the
SimpleUrlHandlerMapping
has been configured to handle
UrlFilenameViewController
.
