The Duke’s Bookstore shipDate tag, defined in tut-install/javaeetutorial5/examples/web/bookstore3/web/WEB-INF/tags/shipDate.tag, is a custom tag that has a simple attribute. The tag generates the date of a book order according to the type of shipping requested.
<%@ taglib prefix="sc" tagdir="/WEB-INF/tags" %> <h3><fmt:message key="ThankYou"/> ${param.cardname}.</h3><br> <fmt:message key="With"/> <em><fmt:message key="${param.shipping}"/></em>, <fmt:message key="ShipDateLC"/> <sc:shipDate shipping="${param.shipping}" />
The tag determines the number of days until shipment from the shipping attribute passed to it by the page tut-install/javaeetutorial5/examples/web/bookstore3/web/bookreceipt.jsp. From the number of days, the tag computes the ship date. It then formats the ship date.
<%@ attribute name="shipping" required="true" %> <jsp:useBean id="now" class="java.util.Date" /> <jsp:useBean id="shipDate" class="java.util.Date" /> <c:choose> <c:when test="${shipping == ’QuickShip’}"> <c:set var="days" value="2" /> </c:when> <c:when test="${shipping == ’NormalShip’}"> <c:set var="days" value="5" /> </c:when> <c:when test="${shipping == ’SaverShip’}"> <c:set var="days" value="7" /> </c:when> </c:choose> <jsp:setProperty name="shipDate" property="time" value="${now.time + 86400000 * days}" /> <fmt:formatDate value="${shipDate}" type="date" dateStyle="full"/>.<br><br>
