試題詳解

121 You are building JSP pages that have a set of menus that are visible based on a user's security role. These menus are hand-crafted by your web-design team; for example, the SalesManager role has a menu in the file /WEB-INF/html/sales-mgr-menu.html. Which JSP code snippet should be used to make this menu visible to the user?
(A) ＜% if (request.isUserInRole ("SalesManager") ) { %＞＜%@ include file=' /WEB-INF/html/sales-mgr-menu.html' %＞＜% } %＞
(B) ＜jsp:if test= 'request.isUserInRole ("SalesManager") '＞＜%@ include file '/WEB-INF/html/sales-mgr-menu.html' /%＞＜/jsp:if＞
(C) ＜% if ( request.isUserInRole("SalesManager") ) { %＞＜jsp:include file='/WEB-INF/html/sales-mgr-menu.html' /＞＜% } %＞
(D) ＜jsp:if test= 'request.isUserInRole("SalesManager")'＞＜jsp:include file '/WEB-INF/html/sales-mgr-menu.html' /＞＜/jsp:if＞
