Java Reference
In-Depth Information
The required JSP will allow us to make use of a 'body' within the
<jsp:useBean>
tag for holding the
<jsp:setProperty>
tag and setting the bean properties to the
form values. When a body is used, an explicit
<
/
jsp:useBean>
closing tag is
required. Assuming that our bean instance is to be called
purchase
, the opening
lines of our JSP will be as follows:
<jsp:useBean id="purchase" class="shopping.OrderBean">
<jsp:setProperty name="purchase" property="*" />
</jsp:useBean>
For retrieving and displaying properties, we can again make use of
<jsp:getProperty>
tags. To emphasise the setting of property values that has
occurred, the names of bean properties will be displayed in the table output. Here's
the code for the JSP…
<HTML>
<%@ page language="java" contentType="text/html" %>
<jsp:useBean id="purchase" class="shopping.OrderBean">
<jsp:setProperty name="purchase" property="*" />
</jsp:useBean>
